The PEOPLE of the State of Illinois, Plaintiff-Appellee,
v.
Willie YOUNG, Defendant-Appellant.
No. 1-99-0450.
Appellate Court of Illinois, First District, Fifth Division.
June 29, 2001.
*1047 *1048 *1049 Robert A. Fisher Law Offices, of Chicago (Robert A. Fisher) of counsel, for appellant.
Richard A. Devine, of Chicago (Renee Goldfarb, Kenneth T. McCurry, John J. Walters, Daniel J. Kollias) of counsel, for appellee.
Justice REID delivered the opinion of the court:
Following a jury trial, Willie Young appeals his conviction of first degree murder resulting from the shooting of Jeffrey Sturghill. Young surrendered himself to police after a warrant had been issued for his arrest. Charged with violations of sections 9-1(a)(1) and (a)(2) of the Criminal Code of 1961 (720 ILCS 5/9-1(a)(1), (a)(2) (West 1998)), Young was convicted and sentenced to 50 years' imprisonment. For the reasons set forth below, we reverse and remand this matter for a new trial.

BACKGROUND
On July 4, 1997, Young and his cousins Russell Warner and Jeannette Junious, who was visiting from Minnesota, left Warner's home and went to 31 East 120th Place, Chicago, Illinois, for a backyard barbeque at the home of Kenneth and Doanita Simmons (Kenneth and Doanita). Ms. Junious remained in the car while Young and Warner joined the party. From this point on there are conflicting accounts of what occurred.
Kenneth testified as a State witness. Though he had moved to Alabama on July 7, 1997, three days after the shooting, he was brought back to Illinois at the expense of the State's Attorney's office. At one time, he told the police he had no information regarding the shooting of Sturghill. After submitting to and flunking a lie detector test, he gave a different version of the events, indicating he did not want to implicate the defendant because he feared him and his gang affiliation. This was the subject of a defense motion in limine, the court ruling that the prior statements would not come in unless the defendant opened the door during the trial. At trial, Kenneth testified on direct examination that Young and Warner arrived at the party just before dark. On cross-examination, however, Kenneth stated that they arrived at 10 or 11 p.m. According to Kenneth, Sturghill and Young began to argue over money owed to Young. He had previously heard them argue over the same $40 on another occasion. Kenneth heard Sturghill tell Young that he had just gotten out of jail and could not pay him until the next day. Young then allegedly pulled a gun on Sturghill, who then ran through the front door inside the house. The argument continued with Young outside and Sturghill inside the house. Young allegedly then told Sturghill to come on outside and talk and that he was not going to "smoke" him. Kenneth then stated that Sturghill told Young, "I'm not coming out, you got a gun and I don't." Kenneth then testified that, after Sturghill came out of the house, Young and Sturghill began to struggle over the gun. During the struggle, a shot was fired and Warner indicated that he was shot in the hand. Kenneth then ran from the scene, looking back to see Young shooting at Sturghill as he fell over the porch railing. Kenneth stated that he did not see Sturghill with a gun at any time during the day. *1050 He further stated that Young told him after the shooting to either "get the steel" or "take the steel." He understood that to mean Young was trying to get him to take his gun. On cross-examination, he admitted that Young was not handing him anything when he said that to him.
Doanita also testified for the State. She had since moved to Missouri and had come to testify at the expense of the State's Attorney's office. She is the sister-in-law of Kenneth and on July 4, 1997, lived on the second floor at 31 East 120th Place. She was mainly an "ear" witness and mostly stated what she allegedly heard from her apartment. Between 11 and 11:30 p.m., she heard three people talking outside the house. As she was familiar with all three voices, she identified them as Young, Kenneth, and a Kenneth Williams. She heard Young say "Everybody around here owes me money and they pay and he gone [sic] pay me too." The two Kenneths then attempted to get Young to leave the individual who owed him money alone. She then stated that she later heard Sturghill say, "Nah man, I ain't opening up the door, I ain't got no gun in my hand and he got a gun in his hand." In contrast to Kenneth's testimony, she said these words were said in response to Kenneth saying "Come on out, you know, I don't need this in my mother's house." This was also allegedly said while Kenneth was banging on the door trying to get Sturghill to come out. Only then did she say that she heard Young say "Ah, man, come on out, I ain't gone [sic] smoke you." She then heard Sturghill say "All right, I ain't got no problem with that." She then heard the door being unlocked. She then heard what she described as a struggle. She did not identify who was involved. She then heard Sturghill say, "Man, I told you I just got out of jail two days ago and I ain't got no money. I'll pay you in the morning, I'll give you some money in the morning." Kenneth had testified that these statements took place in the backyard and not on the porch or in the house.
She then heard a gunshot, and, while looking out of her window, she saw a person running from the house saying, "ah, man, you shot me." She said she saw a hole in the palm of this individual's hand. Then more shots were fired. She was not able to see who fired the shots. She then saw Young running from the house with a gun in his hand. The parties stipulated, however, that if called to testify, Detective Jack Hines of the Chicago police department would testify that he was assigned to this case, he interviewed Doanita and she said that she never saw Young with a gun on the day in question.
In addition to Kenneth and Doanita, the State's case consisted of Joyce Sturghill, Jeffrey Sturghill's mother. She testified, as a life and death witness, to having seen her son when he was alive and again when he was dead.
The State also called John Paulson, an employee of the forensic division of the Chicago police department. He works for the department as an evidence technician forensic investigator. He explained his job as photographing and collecting physical evidence found at a crime scene and transferring that evidence to the Illinois State Police crime lab. Once Paulson received the call about Sturghill's death, he got to the scene approximately 30 minutes later. He indicated the crime scene had been roped off by the patrol officers and was being protected from tampering. After speaking with the police personnel on the scene, Paulson immediately began the processing of the crime scene by taking photographs of the entire location with the body and adjoining areas. Paulson indicated he found the victim lying on his back, face up. There were cartridge cases on the adjoining *1051 porch and one cartridge case near the victim's body. The total number of cartridge cases was seven, with one of that seven being the case near the body. After putting on plastic gloves and breaking out the evidence envelopes, Paulson collected and packed up the evidence. Before fingerprinting Sturghill, Paulson indicated he administered the gunshot residue test to his hands. He then gave inventory numbers to the cartridge cases he found. The cases on the porch were given the inventory number 1839767, while the cartridge found near the body got inventory number 1839766. The gunshot residue test kit was inventoried as 1839768. Paulson then described the bags and envelopes used by the forensic division in their duties. On cross-examination, Paulson reiterated what he found when he processed the crime scene. He was also asked to describe, step-by-step, the process of doing a gunshot residue test on a dead person's hands to determine the presence of lead, antimony and barium.
Following the testimony of Paulson, the trial court was told that Dr. Barry Lifschultz, a staff forensic pathologist with the Cook County medical examiner's office, had once again modified his opinion regarding the nature of the entrance and exit wounds on Sturghill's body. This announcement was made to the trial court a mere 15 minutes before Lifschultz was set to testify. The assistant State's Attorney in this case had just, one day before trial began, advised the defense counsel that Dr. Lifschultz had advised the prosecutor that he would give opinions on entrance and exit wounds. The trial court was asked to bar testimony regarding the entrance and exit wounds. In explanation of the change of opinion, the trial court learned that Lifschultz had further reviewed the photographs and was prepared to give a more thorough explanation of the entrance and exit wounds and was now able to render an opinion about the wound on Sturghill's leg. The trial court indicated it would not prevent Lifschultz from testifying thoroughly about the entrance and exit wounds. Although the trial court indicated it did not feel the leg testimony would prejudice the defendant's case, it offered the defense a chance to have Lifschultz testify out of sequence. In spite of the trial court's offer, and in spite of defense objections to the late disclosure of the new opinions by the State, the defense indicated it was ready to proceed. The defense counsel admitted he was lacking in the expertise necessary to appropriately cross-examine Dr. Lifschultz on his new and improved medical opinions. In spite of this, defense counsel did not seek a continuance because he did not wish to break his four-term trial demand.
Following the colloquy with the trial court about the change in testimony, Lifschultz was tendered to the trial court as an expert witness in forensic pathology. He testified to the autopsy process in general and the autopsy of Jeffrey Sturghill in particular. He found three through-and-through gunshot wounds, a small abrasion over the left eye and a small abrasion on the back of the right ankle. Lifschultz found that the abrasions were consistent with a fall over the railing. He testified that he can tell the difference between entrance and exit wounds because of the tearing of the skin associated with exit wounds and the presence of specific abrasions of the tissue surrounding the entrance wounds. Lifschultz concluded that the wound at the side of the back was an entrance wound. The wound at the left side of the back was also an entrance wound. The corresponding wound on the right side of the belly was an exit wound. There were also gunshot wounds to the left hip and lower right leg, the photographs *1052 of which were marked by the witnesses as to entrance and exit.
On cross-examination, Lifschultz was questioned as to how he could be so certain at trial as to which were entrance and exit wounds even though there were no such designations made at the time of the autopsy. At no point in the report did Lifschultz document which were entrance and which were exit wounds. He was then questioned as to the change in his opinions from the time they were originally made until 15 minutes prior to the testimony for which he was being cross-examined. Lifschultz claimed his new opinion was a refinement of his original opinion.
Next to testify was Scott Rochowicz, an employee of the Illinois State Police Forensic Science Center in Chicago, Illinois. He testified to the gunshot residue test. He found elevated levels of barium, antimony and lead on the decedent's hands. He found the levels to be inconclusive of gunshots because those levels were not as high as he would have expected, though he admitted he found levels that were elevated above the amounts normally found on the general population. He did not test the decedent's clothing for gunshot residue, even though he admitted there could have been residue there.
Finally, the State called Michael McDermott, a detective with the Chicago police department. He testified to the process he went through while searching for Young. This process was cut short when Young turned himself in.
The defendant's version of the events is different. Warner testified that he was an assistant family teacher at Maryville Academy. Young is his first cousin and he has known him all of his life. On July 4, 1997, he was at his mother's house at 69th and Justine together with his mother, her boyfriend, his sister, his half sister Jeannette Junious, nephews, and his cousins, including Young. At 10 p.m., he, Young and his half sister decided to go visit some friends on 120th Street. Kenneth was Young's friend. He drove. He and Young got out of the car and went to the backyard of the house. Young was talking to Kenneth when some third person started making some comments and then drew a gun. Kenneth and Young told him to put the gun up and he did. Then he saw the three of them go into the house. He followed them into the house. Young and Kenneth were having a conversation and the third person (Sturghill) was getting into their conversation. At that point, Sturghill drew his gun again. Warner, Young and Kenneth spoke to him and told him to calm down and put the gun up. Sturghill appeared to Warner to be kind of frustrated, but he listened and went out on the front porch. Warner then followed him out on the front porch. On the porch, Warner said he was trying to calm Sturghill down and get him to put the gun up. Young and Kenneth were still inside of the house. Sturghill motioned like he was going to go back inside the house. Warner stepped in front of him and told him to put the gun up. After about two minutes, Sturghill appeared to have calmed down and put the gun back in his waist. Warner started to go into the house and saw out of his peripheral vision that Sturghill was raising the gun. Warner thought that he was about to be shot. He went for the west side of the porch and jumped off of the porch. He felt a twinge of pain in his left hip. He reached back to feel it and then saw blood on his hand. He then realized he had been shot. He then screamed "I been shot." He pulled himself up on the fence and then got into his car. Warner's clothing that he wore that day and his wound in the left hip near the buttocks were displayed to the jury. On cross-examination, he admitted that he did not *1053 go to a hospital. He did not see Sturghill get killed. On July 26, 1997, the police picked him up for questioning. A nine-page statement was taken and he was instructed to sign each page by an assistant State's Attorney. He then testified that he tried to tell the police about the decedent having a gun and about being shot by the decedent, but they did not want to hear that and he did not put that in the statement when he talked to the assistant State's Attorney. He felt intimidated by the police officer who was present at all times. He testified that the police said he could be charged as an accessory to murder and they did not want to hear anything that sounded favorable to his cousin. He was held in custody for almost two days before he spoke to the assistant State's Attorney. The statement was partially disclosed on cross-examination to the effect that Warner said he had gone to a liquor store and returned to hear three voices arguing along the front sidewalk on the south side of 120th Place (two of which belonged to Young and Kenneth) and that he heard gunshots coming from the front porch. After he heard the shots fired, he got down on his hands and crawled back to his car, where his sister was, and that he never looked back to see who was shooting. The statement also said he did not recall looking at his hands or seeing any blood on them and that, as soon as he got in the car, Young got in on the passenger side. He stated that he made some of this up in order to placate the police. He was asked if he knew Ms. Simmons and the following exchange took place:
"A: No, I do not. I know of her. I do not know her.
Q: Can you think of any reason in the world why she would testify that you are a bald face liar?
Defense Counsel: Objection.
THE COURT: Sustained. Don't answer that."
The defendant took the stand in his own behalf. He testified that he was 31 years old and had a year in college at North Community College. On July 4, 1997, he was at his cousin's house. Several people were there. He, Warner, and Junious went to visit one of his friends, Kenneth Simmons. Warner drove, Junious was in the front passenger seat, and he was in the back seat. He and Warner got out of the car at Kenneth's house and left Junious in the car. After Warner knocked on the front door, Young suggested that they go around back, which they did. In the backyard were Rico, Deuce, Sturghill, Kenneth, Tiny, and Kenneth's sister Valerie. They were back there barbequing. He spoke to a few of the people and then asked Kenneth about some money that Kenneth owed him. Kenneth said he did not have it. Young then said "you never pay me on time whenever I give you money." Then Jeffrey Sturghill asked Young if he was selling cocaine over there. Young said it was none of his business. Sturghill became angry and began to shout at Young. Young shouted back. The confrontation did not get physical, however. Rico, Deuce and Kenneth stepped in between them saying that it was no cause for that. Kenneth then said "we're not going to have that here." Then Sturghill pulled out a gun. Rico and Deuce told him to put it up. Sturghill uttered a profanity and put his gun away. Young then said that he did not need this "s__t" and he then told Sturghill that only a "b___h" would shoot him in the back and then turned and walked away. Kenneth then invited him into the house to talk to him. Young and Kenneth went into the house. Sturghill also came into the house with Warner. Kenneth asked Young to stay because nothing would happen to him over there. Young indicated that he should leave. Sturghill *1054 then said to Young that when he stepped outside, Sturghill would "whip his ass." Kenneth told Sturghill to "chill out, that it is not going to happen" in his mother's house. Sturghill went outside on the front porch. Warner followed him outside. Shortly thereafter they heard a gunshot. Young and Kenneth went to the door and paused for a while. Young looked out and heard Warner say he had been shot. Young saw Warner walking along the sidewalk along the gate. Young then stepped out of the door. Sturghill turned to him with his gun up. Young then shot Sturghill.
The jury deliberated for less than two hours before returning a guilty verdict. Young was sentenced to 50 years, from which this appeal follows.

I
Young claims the evidence presented was insufficient to convict him of first degree murder. He argues that, once a defendant claims a shooting was done in self-defense, the State must not only prove the elements of the offense beyond a reasonable doubt, but also that the shooting was not done in self-defense. Young argues that the physical and scientific evidence corroborated his theory that the shooting was the result of self-defense. He points to the spent cartridge case found near Sturghill's body. That cartridge case was found not to be from the firearm used to shoot Sturghill. Young claims that the State offered little more than speculation for how that cartridge case got next to the body. According to Young, the scientific tests performed on Sturghill showed elevated levels of lead, antimony and barium, all elements associated with the firing of guns. While the tests were deemed inconclusive, Young attaches significance to the fact that the levels of those elements were higher than the levels that would likely be found on the hands of an ordinary citizen who had not fired a gun.
Young also argues that the gunshot wounds were consistent with the claim of self-defense. Dr. Lifschultz found that one of the bullets entered at the left side of Sturghill's back and exited at the right side of the belly, traveling at a downward angle. Young claims this is consistent with his testimony that he shot Sturghill as Sturghill started to turn back toward him. In light of all of the physical and scientific evidence, Young claims he was justified in shooting Sturghill.
Young next argues that prosecutorial misconduct deprived him of due process and a fair trial. Since none of the State's witnesses were able to observe all of the events and there was so much scientific evidence, Young argues this is a closely balanced case. In such closely balanced cases, Young argues, the prosecutorial misconduct should be treated as considered plain error. Young claims the prosecutor improperly questioned him on the credibility of other witnesses, then made the subject of the improper cross-examination the centerpiece of his closing argument to the jury, in that he repeatedly tried to bolster the credibility of the State's witnesses all the while undermining his own credibility. The prosecutor even characterized the questions as "trick questions."
Next, Young claims the prosecution improperly shifted the burden of proof to the defendant. This was done, according to Young, by consistently misstating the jury's function and the State's burden of proof. Instead of telling the jurors that the State had to prove its case against Young beyond a reasonable doubt, the prosecutor told the jury, "[W]hat you do need to decide this case is do you believe Doanita and Kenneth Simmons or do you believe Russell Warner and Willie Young." *1055 Young claims it was wrong for the prosecutor to suggest that the jury's determination of whom it believed would lead it to both the truth of the case and a verdict of guilty. Since no one in this case disputes that Young shot Sturghill, thus causing the fatal injuries, the issue for the jury to decide was whether Young had the requisite mental state for first degree murder. The question is whether the shooting was in self-defense, and therefore justified. As the issue was presented to the jury, according to Young, the burden was improperly shifted to him. This had the effect of compromising the fairness of the judicial process by requiring Young to prove his innocence instead of making the State prove his guilt.
Young next claims he was prejudiced when the State cross-examined him on his postarrest silence. The prosecutor, after hearing some of Young's testimony, asked him whether the trial testimony was the first time he had said anything regarding the details of his self-defense claim. He then later commented on the postarrest silence in the closing argument. According to Young, this improperly implicated his right to remain silent because it was intended to invite the jury to infer that the defense was a recent fabrication.
Next, Young claims the prosecutor improperly questioned him as to other crimes and bad acts. Young made a motion for discovery which specifically requested disclosure of prior acts or convictions of a similar nature for proof of knowledge, intent, motive or modus operandi. The State's answer to the discovery motion listed no prior bad acts or convictions. Young subsequently made a motion in limine relative to bad acts, which was granted by the trial court. In spite of the motion in limine, the prosecutor began to violate the order by referring to the shooting having been over a drug debt, even though no such evidence was presented in the case. When cross-examining Young, the prosecutor kept referring to prior bad acts. Young maintains this was only done to prejudice him in the eyes of the jury.
Finally, Young argues that the prosecutor improperly vouched for witnesses and injected his personal opinions as to the evidence.

II
The standard of appellate review of a criminal case is one of great deference to the trier of fact since it is not the function of the appellate court to retry the defendant. People v. Smith, 318 Ill. App.3d 64, 251 Ill.Dec. 639, 740 N.E.2d 1210 (2000). Upon a challenge to the sufficiency of the evidence, a reviewing court must determine whether, after viewing the evidence in a light most favorable to the State, any rational trier of fact could find the essential elements of the offense beyond a reasonable doubt. People v. Daniel, 311 Ill.App.3d 276, 282, 243 Ill.Dec. 678, 723 N.E.2d 1279 (2000). Criminal convictions will not be set aside unless the evidence is so improbable or unsatisfactory as to create a reasonable doubt of the defendant's guilt. People v. Waldrup, 317 Ill.App.3d 288, 293, 251 Ill.Dec. 241, 740 N.E.2d 71 (2000). It is the function of the jury to assess the credibility of the witnesses, the weight to be given their testimony and the inferences to be drawn from the evidence. On appeal, a reviewing court, considering all the evidence in the light most favorable to the prosecution, must determine whether any rational fact finder could have found beyond a reasonable doubt the essential elements of the crime. Waldrup, 317 Ill.App.3d at 293, 251 Ill.Dec. 241, 740 N.E.2d 71, citing People v. Peeples, 155 Ill.2d 422, 487, 186 Ill.Dec. 341, 616 N.E.2d 294 (1993).
*1056 Whether a killing is justified under the law of self-defense is a question of fact to be determined by the trier of fact. People v. Felella, 131 Ill.2d 525, 533, 137 Ill.Dec. 547, 546 N.E.2d 492 (1989). "Self-defense is an affirmative defense, and once a defendant raises it, the State has the burden of proving beyond a reasonable doubt that the defendant did not act in self-defense, in addition to proving the elements of the offense charged beyond a reasonable doubt." People v. Grayson, 321 Ill.App.3d 397, 401, 254 Ill. Dec. 420, 747 N.E.2d 460 (2001); People v. Jeffries, 164 Ill.2d 104, 207 Ill.Dec. 21, 646 N.E.2d 587 (1995). "The elements of self-defense are (1) that unlawful force is threatened against a person; (2) that the person threatened is not the aggressor; (3) that the danger of harm is imminent; and (4) that the use of force was necessary." People v. White, 293 Ill.App.3d 335, 338, 227 Ill.Dec. 697, 687 N.E.2d 1179 (1997). Because the jury determines witness credibility, draws reasonable inferences from testimony, and resolves conflicts in the evidence, it need not accept a defendant's claim of self-defense. People v. Boyd, 307 Ill.App.3d 991, 995, 241 Ill. Dec. 445, 719 N.E.2d 306 (1999). The standard of review for this issue is whether, taking all of the evidence in the light most favorable to the State, any rational trier of fact could have found, beyond a reasonable doubt, that the defendant did not act in self-defense. People v. Lee, 311 Ill.App.3d 363, 367, 243 Ill.Dec. 958, 724 N.E.2d 557 (2000).
Part of what makes this a close case is the presence of "inconclusive" evidence, like the fact that the victim's hands had a higher-than-expected level of those chemicals normally associated with the firing of a weapon and that the prosecution did not test the victim clothing for similar residue. Also, the presence by the victim's body of the mystery cartridge casing tends to lend an air of credibility to Young's self-defense claim. When dealing with a close case, a reviewing court can apply the plain error rule to consider not only those issues properly presented, but those that may not have been properly raised before the trial court. This plain error rule allows an appellate court to consider those issues when the evidence is closely balanced or the errors in the case are "so fundamental and of such magnitude that the defendant was denied a fair trial." People v. Rios, 318 Ill.App.3d 354, 361, 252 Ill.Dec. 159, 742 N.E.2d 409 (2000), citing People v. Lucas, 151 Ill.2d 461, 482, 177 Ill.Dec. 390, 603 N.E.2d 460 (1992). Where errors claimed on appeal are not individually considered sufficiently egregious to entitle the defendant to a new trial nevertheless create a pervasive pattern of unfair prejudice to defendant's case, a new trial may be granted on the ground of cumulative error. People v. Mendez, 318 Ill.App.3d 1145, 1154, 253 Ill.Dec. 319, 745 N.E.2d 93 (2001), citing People v. Blue, 189 Ill.2d 99, 244 Ill.Dec. 32, 724 N.E.2d 920 (2000). A substantial right has been denied if the error affected the proceedings to such a degree that we cannot confidently state that the defendant's trial was fundamentally fair. People v. Keene, 169 Ill.2d 1, 214 Ill.Dec. 194, 660 N.E.2d 901 (1995). This court will act on error that is of such gravity that it threatens the very integrity of the judicial process. People v. Blue, 189 Ill.2d 99, 244 Ill.Dec. 32, 724 N.E.2d 920 (2000).
Every defendant is entitled to fair trial free from prejudicial comments by the prosecution. People v. Billups, 318 Ill.App.3d 948, 958, 252 Ill.Dec. 397, 742 N.E.2d 1261 (2001). It is well settled that the prosecutor has wide latitude in making closing remarks. Mendez, 318 Ill.App.3d at 1152, 253 Ill.Dec. 319, 745 N.E.2d 93. *1057 Improper remarks will not merit reversal unless they result in substantial prejudice to defendant, in light of the context of the language used, its relationship to the evidence, and its effect on the defendant's right to a fair and impartial trial. Billups, 318 Ill.App.3d at 958-59, 252 Ill.Dec. 397, 742 N.E.2d 1261, citing People v. Barker, 298 Ill.App.3d 751, 757, 232 Ill.Dec. 854, 699 N.E.2d 1039 (1998). The prosecutor's argument must be examined in its entirety and the complained-of comments placed in their proper context. Mendez, 318 Ill. App.3d at 1152, 253 Ill.Dec. 319, 745 N.E.2d 93, citing People v. Morgan, 142 Ill.2d 410, 154 Ill.Dec. 534, 568 N.E.2d 755 (1991). A court must be aware that, in certain circumstances, "improper comment by counsel may be cured by providing proper instructions of law." Mendez, 318 Ill.App.3d at 1152, 253 Ill.Dec. 319, 745 N.E.2d 93, citing People v. Hobley, 159 Ill.2d 272, 202 Ill.Dec. 256, 637 N.E.2d 992 (1994). Reversible error results when comments by a prosecutor substantially prejudice a defendant, causing one to question whether the guilty verdict resulted from those comments. People v. Castaneda, 299 Ill.App.3d 779, 784, 233 Ill.Dec. 916, 701 N.E.2d 1190 (1998). In other words, "where a prosecutor's remarks exceed the bounds of proper comment, a reviewing court should not disturb the verdict unless it can be said that the remarks in question resulted in substantial prejudice to the accused such that absent those remarks the verdict would have been different." People v. Joyner, 317 Ill.App.3d 93, 105, 250 Ill.Dec. 831, 739 N.E.2d 594 (2000).
In addition to comments, a prosecutor can overstep his or her bounds by conduct as well. As alleged by Young, this can include improper questioning of witnesses. By asking Young to comment on the testimony of the medical examiner, and why other witnesses might lie in their testimony, the prosecutor improperly removed from the province of the jury the duty to determine the credibility of witnesses. While it is certainly a fine line between trial tactics and the using of cross-examination to invade the province of the jury, these facts raise a sufficient specter of impropriety, especially in light of the close nature of the evidence, to question whether Young received the fair trial to which he is constitutionally entitled. The same is true of the prosecutor's questions that were an attempt to trick defendant into bolstering the opposition witnesses at his own expense. It would be different if Young had opened the door to such questions by claiming he was the victim of a plot or conspiracy. When the prosecutor referred to his efforts as a trick question, that suggests his conduct was intentional.
Also complained of, the prosecutor confused the jury by misstating the jury's responsibilities and the State's burden of proof. "It is well established that a prosecutor's misstatements of law in closing argument can be grounds for reversal. See United States v. Bohle, 445 F.2d 54 (7th Cir.1971); United States v. Phillips, 527 F.2d 1021 (7th Cir.1975). Included within the restrictions are statements that in effect distort the burden of proof by suggesting incorrectly what the jury must find in order to reach a certain verdict." People v. Crossno, 93 Ill.App.3d 808, 820, 49 Ill.Dec. 137, 417 N.E.2d 827 (1981), quoting United States v. Vargas, 583 F.2d 380, 386 (7th Cir.1978). This is similar to what happened to Young. The prosecutor told the jury that, to determine guilt or innocence, they needed to decide which witnesses it believed. "The test is, of course, not which side it more believable, but whether, taking all of the evidence in the case into consideration, guilt as to every essential element of the charge has been proven beyond a reasonable doubt." *1058 Crossno, 93 Ill.App.3d at 822, 49 Ill.Dec. 137, 417 N.E.2d 827.
This prosecutor was also wrong in cross-examining Young regarding his postarrest silence, prior bad acts and other crimes, as well as improperly vouching for certain witnesses and interjecting his own opinions regarding the evidence, again infringing on the province of the jury.
Next, Young claims he was denied his right to a fair trial due to ineffective assistance of counsel. The Illinois Supreme Court recently discussed the issue of ineffective assistance of counsel in the case of People v. Hall, 194 Ill.2d 305, 337-38, 252 Ill.Dec. 653, 743 N.E.2d 521 (2000), as follows:
"Claims of ineffective assistance of trial counsel are evaluated under the two-prong test set forth in Strickland v. Washington, 466 U.S. 688 [668], 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). First, a defendant must demonstrate that counsel's performance was deficient in that it fell below an objective standard of reasonableness. Strickland, 466 U.S. at 687-88, 104 S.Ct. at 2064, 80 L.Ed.2d at 693. Second, a defendant must show prejudice by demonstrating that there is a reasonable probability that, but for counsel's unprofessional errors, the outcome of the proceeding would have been different. Strickland, 466 U.S. at 694, 104 S.Ct. at 2068, 80 L.Ed.2d at 698. A reasonable probability is a probability sufficient to undermine confidence in the outcome, namely, that counsel's deficient performance rendered the result of the trial unreliable or the proceeding fundamentally unfair. Strickland, 466 U.S. at 694, 104 S.Ct. at 2068, 80 L.Ed.2d at 698; People v. Evans, 186 Ill.2d 83, 93 [237 Ill.Dec. 118, 708 N.E.2d 1158] (1999). A court may resolve a claim of ineffective assistance of counsel by reaching only the prejudice prong, as a lack of prejudice renders irrelevant the issue of counsel's alleged deficient performance. See Strickland, 466 U.S. at 697, 104 S.Ct. at 2069, 80 L.Ed.2d at 699; Evans, 186 Ill.2d at 94 [237 Ill.Dec. 118, 708 N.E.2d 1158]."
We find ineffective assistance in several places, first, from the failure of defense counsel to step up and object to the conduct of the prosecutor and also in the admission defense counsel made in open court that he lacked the requisite expertise to appropriately cross-examine experts on their opinions. Although the trial court indicated that a continuance would be acceptable to give time to better prepare, Young's trial counsel indicated readiness. Admittedly, trial counsel was placed on the horns of a dilemma when facing the defendant's competing interests of having a speedy trial with having effective representation at trial. Additionally, trial counsel's representation fell below the minimal Strickland level of effectiveness during cross-examination because he not only bolstered the testimony of the experts, but repeatedly referred to his inability to properly defend against those expert opinions. Trial counsel's only job was to explain ways the opinions of the expert were consistent with the theory of self-defense. If counsel is mounting a self-defense argument, then effective representation requires either refuting opposition testimony or simply developing it in a way that is consistent with the theories being espoused. Additionally, though failure to do this is not necessarily a trial error, effective assistance in mounting a self-defense claim dictates that counsel should have ordered gunshot residue tests of Sturghill's clothing, especially when the State seems unable or unwilling to do so as part of its normal investigative process.
In light of the foregoing, including prosecutorial misconduct, cumulative error and *1059 ineffective assistance of counsel, the decision of the trial court is reversed and the cause is remanded for a new trial.
Reversed and remanded.

Justice THEIS, specially concurring:
While I agree with the majority's result, I specially concur to clarify the issue regarding the prosecutor's practice of asking defendant to comment on the veracity of witnesses. I agree with the majority that the evidence in this case is closely balanced and, thus, warrants review under the plain error doctrine. People v. Lofton, 194 Ill.2d 40, 73, 251 Ill.Dec. 496, 740 N.E.2d 782, 801 (2000). Here, defendant asserted self-defense and offered witnesses to corroborate his account of the events, making credibility a significant issue. Forensic tests revealed elevated levels of lead, barium, and antimony on the victim's hands, giving rise to an inference that the victim fired a gun, although the tests were deemed inconclusive. Further, the police determined that a shell casing found near the victim's body did not come from defendant's weapon. The medical examiner's report concerning entrance and exit wounds on the victim could also lend support to defendant's self-defense claim. Thus, the evidence is closely balanced and is properly reviewed under the plain error doctrine.
In this case, the prosecutor asked defendant several times to comment on the State witnesses' veracity: "So the medical examiner lied when he said that this was an entrance wound?"; "So you can't think of any reason why he [Kenneth Simmons] would lie about what you did, can you?"; "We expect our enemies to lie on us. It [sic] was your friend, wasn't he?"; and "Can you think of any reason why she [Doanita Simmons] would lie?" Defendant answered that he did not know what the medical examiner said, that Kenneth and Doanita were his friends and he did not know of any reason why they would lie.
The prosecution's practice of asking a criminal defendant to comment on the veracity of other witnesses who have testified against him has consistently and repeatedly been condemned by this court because such questions intrude on the jury's function of determining the credibility of witnesses and serve to demean and ridicule the defendant.

Hicks, 133 Ill.App.2d 424, 434, 273 N.E.2d 450, 458 (1971).
While this practice has generally been deemed harmless error where evidence of defendant's guilt was overwhelming, here, as discussed above, the evidence was closely balanced and the credibility of the witnesses was a crucial factor underlying the jury's determination of defendant's guilt or innocence. Further, the State compounded this error by arguing during closing arguments that the jury should find the State's witnesses, and not defendant, credible, leading to a guilty verdict. The prosecutor referred to his questions to defendant as "trick" questions and stated that the State's witnesses had "no motive to lie." In light of the State's numerous instances of prosecutorial misconduct, this court's repeated condemnation of this practice, and the closely balanced evidence in this case, the State's questioning of defendant with respect to the veracity of adverse witnesses was not harmless error. Accordingly, I concur with the result of the majority in reversing and remanding the judgment of the circuit court.
Justice GREIMAN, dissenting:
The majority has chosen to address most[1] of defendant's claims of prosecutorial misconduct and ineffective assistance of counsel under the plain error rule (134 Ill.2d R. 615(a)) because it finds the facts of the case to be closely balanced. For this, it points to what it terms "inconclusive evidence," i.e., the higher levels of lead, antimony and barium on the victim's hands as well as the proximity of the "mystery cartridge casing" to the victim's body. However, because the bulk of the remaining evidence adduced at trial conforms to the theory advanced by the State, I disagree that plain error may be used to sidestep the general rule of waiver as outlined in People v. Enoch, 122 Ill.2d 176, 186, 119 Ill.Dec. 265, 522 N.E.2d 1124 (1988).
In this case, substantial evidence was presented to show that the defendant did not act in self-defense in killing the victim. This includes the testimony of Kenneth Simmons, who stated that defendant instigated the argument with the victim regarding the $40 and that defendant first pulled his gun demanding the money in an "unfriendly" manner. Doanita Simmons heard this argument through open the open windows of her house and was able to corroborate Kenneth's testimony. Both Kenneth and Doanita heard the defendant state that "everybody around here owes me money and they pay[,] and he's gone [sic] to pay me too." After the argument escalated, Kenneth stated that he tried to convince the defendant to leave the victim alone, and that the victim ran into the house through the back door. Kenneth asked the victim to come outside, and both Kenneth and Doanita heard the victim state that he did not want to leave the house because he was unarmed and the defendant was not. Kenneth's testimony that he never saw the victim with a gun corroborated this statement. Both Kenneth and Doanita also heard the defendant *1061 ask the victim to come outside and promise not to shoot him. Upon exiting the house, the victim and the defendant became involved in a physical struggle. Kenneth stated that, at that point, a shot was fired and he saw defendant, with his arm extended, shoot the victim "five or six times."
The credibility of the witnesses and the weight of the evidence are determinations within the province of the jury. People v. Sutherland, 155 Ill.2d 1, 17, 182 Ill.Dec. 577, 610 N.E.2d 1 (1992). It was within the jury's province to believe Kenneth and Doanita's version of the incident rather than the defendant's version and it was within the jury's province to believe that given the number and location of gunshot wounds the defendant inflicted, the defendant was not acting in self-defense. Moreover, a "closely balanced" case is one where the outcome of the case would have to be different had the impropriety not occurred. People v. Young, 128 Ill.2d 1, 47, 131 Ill.Dec. 86, 538 N.E.2d 461 (1989). In concurring with the jury's verdict, I also do not find that the evidence is so closely balanced factually that the alleged ineffective assistance of counsel and prosecutorial error could have altered the outcome of this case. Accordingly, I find that the claims that were not properly preserved by objection at trial and in a written posttrial motion are waived.
However, even assuming that the facts were close enough to require review of defendant's claims, I do not believe that any of the alleged errors, whether taken individually or cumulatively, preserved or unpreserved, constitute reversible error. The majority holds that the cumulative effect of the prosecution's improper questioning of the defense witnesses, its misstatement of the burden of proof, its improper vouching for certain witnesses, and its comments regarding the defendant's postarrest silence and his prior criminal background deprived defendant of a fair trial. In addition, it finds defendant's counsel ineffective for failing to make timely objections and for indicating "that he lacked the requisite expertise to appropriately cross-examine experts on their opinions," thereby bolstering those opinions. Op. 1058. I respectfully disagree.
Most of the errors of which defendant complains have been found by Illinois courts not to constitute reversible error when found to have as limited an impact on the proceedings as I believe these alleged errors have in the present case. See, e.g., People v. Turner, 128 Ill.2d 540, 557, 132 Ill.Dec. 390, 539 N.E.2d 1196 (1989) (queries regarding why another witness testified as he did held to be proper); People v. Riley, 63 Ill.App.3d 176, 184-85, 19 Ill.Dec. 874, 379 N.E.2d 746 (1978) (questioning of another witness' veracity held improper, but generally not reversible error); People v. McKinley, 242 Ill.App.3d 124, 131-32, 182 Ill.Dec. 186, 609 N.E.2d 720 (1992) (prosecutor's comment on defendant's failure to produce an expert held to be proper where prosecutor does not assert that defendant had an obligation to prove the expert wrong); People v. Pecoraro, 144 Ill.2d 1, 16, 161 Ill.Dec. 296, 578 N.E.2d 942 (1991) (comment that the jury's disbelief in certain witnesses will lead to a not-guilty verdict held to be proper where the prosecution's version of the incident varies substantially from the version given by the defense); People v. Bailey, 249 Ill.App.3d 79, 82, 186 Ill.Dec. 488, 616 N.E.2d 678 (1993) (holding that it is not error per se for a prosecutor to use the first person in addressing the jury); People v. Hall, 194 Ill.2d 305, 339, 252 Ill.Dec. 653, 743 N.E.2d 521 (2000) (holding that although the erroneous admission of other-crimes evidence ordinarily calls for reversal, the evidence must have been a material factor in the defendant's conviction such that, without the evidence, the *1062 verdict likely would have been different); People v. Buss, 187 Ill.2d 144, 245-46, 240 Ill.Dec. 520, 718 N.E.2d 1 (1999) (holding that counsel was not ineffective where defendant has not demonstrated prejudice resulting from his counsel's failure to object to the portion of the argument at issue); People v. Steading, 308 Ill.App.3d 934, 939, 242 Ill.Dec. 510, 721 N.E.2d 789 (1999) (holding that counsel is not ineffective where defendant has not demonstrated how any further investigation of the witness would have changed the outcome of the case); People v. Harris, 182 Ill.2d 114, 158, 230 Ill.Dec. 957, 695 N.E.2d 447 (1998) (holding that defense counsel's admission of his own ineffectiveness is not determinative of the issue).
However, I was initially inclined to agree with the majority that the prosecution committed reversible error in questioning defendant about his postarrest silence, thereby violating the due process clause of the fifth amendment. U.S. Const., amend. V. The case relied upon by the State in its motion to cite additional authority, People v. Colts, 269 Ill.App.3d 679, 206 Ill.Dec. 220, 645 N.E.2d 225 (1993), has convinced me otherwise. There, the prosecutor asked defendant when he first told anyone about his alibi. On appeal, defendant contended that question drew attention to his postarrest silence, in violation of Doyle v. Ohio, 426 U.S. 610, 96 S.Ct. 2240, 49 L.Ed.2d 91 (1976). We held:
"The prosecutor did not ask about defendant's silence during police questioning; instead, the prosecutor's question covered many conversations with private parties over an extended period of time. In the months prior to trial, defendant had ample opportunity to discuss his case with counsel and others, under circumstances in which a person would normally mention where he had been, if he had not been at the crime scene. The trial court properly overruled defendant's objection to the question." Colts, 269 Ill.App.3d at 692, 206 Ill.Dec. 220, 645 N.E.2d 225.
Because the prosecutor's query in the present case, "[s]o the first time you are telling anybody about that [the self-defense theory] is today here," is indistinguishable from that in Colts, I believe that controlling case law compels a finding that no Doyle violation occurred. Without this violation, I find that none of the other alleged errors, as previously discussed, rise to the level of grave, reversible error. Consequently, I respectfully dissent.
NOTES
[1]  In his brief, defendant alleges 27 errors, yet he has properly preserved only four of these alleged errors for review.
