Gregory MOSS, Appellant,
v.
STATE of Indiana, Appellee.
No. 2-1273A266.
Court of Appeals of Indiana, Second District.
August 26, 1975.
*142 Harriette Bailey Conn, Public Defender, David P. Freund, Deputy Public Defender, Indianapolis, for appellant.
Theodore L. Sendak, Atty. Gen., Russell D. Millbranth, Deputy Atty. Gen., Indianapolis, for appellee.
SULLIVAN, Presiding Judge.
Gregory Moss was charged on December 13, 1971 with possession of a narcotic drug (heroin), in violation of IC 1971, XX-XX-X-X, Ind. Ann. Stat. § 10-3520 (Burns 1956) (Repealed 1973). Trial was held before the court without jury on February 25, 1972. Moss was found guilty as charged and sentenced accordingly. His Belated Motion to Correct Errors, pursuant to Post Conviction Remedy Rule 2, was overruled, and he brings this appeal.
We affirm.
The facts ascertainable from the record reveal that at about 1:00 P.M. on October 13, 1971, Indianapolis Police Officer Ernest L. Miller, acting on the basis of information of undisclosed content from a previously reliable informant, placed under surveillance a car parked at North and Blakely Streets in Marion County, Indiana. Moss was sitting in the car next to the window on the passenger side. Two other persons sat in the front seat. Officer Miller stated that he observed the car for "about ten or fifteen minutes" during which time he saw "several" persons approach the passenger's side of the car, talk to Moss and that they "stuck their hand inside the car." Miller stated that the persons who had approached the car were known to him to be drug addicts. Believing that narcotics were being sold, Miller aproached the passenger side of the car and identified himself as a police officer, at which time he saw Moss "take his right hand and go between his legs." Fearing that Moss might have a weapon, Miller asked him and the other occupants to step out of the car for a pat-down weapon search. As they got out of the car, Miller noticed a cigarette package on the seat where Moss had been sitting. The officer picked up the cigarette package, looked inside it and discovered four tinfoil packages containing a white powdery substance, later shown to be heroin.
When the State offered the cigarette package and the bindles of heroin Officer Miller had found inside it, Moss objected, asserting that this evidence was the product of an unlawful search and seizure.
Two issues are properly presented to this court:
1. Did the trial court err in overruling ruling Moss's objection to the admission of the cigarette package and its contents?
2. Is the evidence sufficient to sustain the conviction?

I
Moss argues that Officer Miller's actions in removing the cigarette package from the car and examining its contents constituted a search of the vehicle and its contents. Moss's theory is that the search was unlawful and its product therefore inadmissable because the officer acted without a warrant and without probable cause to arrest or search without a warrant.
The State responds that Officer Miller's conduct was not a "search" at all but rather a seizure by him of evidence in his plain view as he stood in a position where he had a right to be. The State's *143 theory is that Miller had a right to be in a position to observe the cigarette package in plain view on the front seat of the car because he was in the process of conducting an investigative stop and protective "frisk" for weapons pursuant to IC 1971, 35-3-1-1 through 35-3-1-3, Ind. Ann. Stat. §§ 9-1048 - 9-1050 (Burns Supp. 1974) and Terry v. Ohio (1968), 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889. Prior to its discussion of the "plain view" doctrine in its brief, the State seems to suggest that the seizure of the cigarette package and its contents might also be justifiable under a "search incident to arrest" theory as per Frasier v. State (1974), Ind., 312 N.E.2d 77; Taylor v. State (1974), Ind. App., 313 N.E.2d 92, and Sizemore v. State (1974), Ind. App., 308 N.E.2d 400, these cases being an extension of Gustafson v. Florida (1973), 414 U.S. 260, 94 S.Ct. 488, 38 L.Ed.2d 456 and United States v. Robinson (1973), 414 U.S. 218, 94 S.Ct. 467, 38 L.Ed.2d 427.
While our reading of the cases, both from this state and other jurisdictions, suggest that persuasive arguments could be framed for opposing views on the legality of the seizure, we need not resolve this issue. The record reveals that the trial court properly admitted other evidence which, standing alone, is sufficient to sustain the conviction. Any error which may have occurred in the admission of the heroin therefore is not grounds for reversal.
Officer Miller testified without objection that he had obtained the cigarette package from "the front seat of the car that Mr. Moss was sitting in." No objection was made when the officer stated that he had placed the cigarette package inside a yellow envelope which he then sealed, initialed, and "put it in the narcotic dropbox." Officer Miller's statement that he had personally removed the initialed envelope from the narcotic vault on the day of the trial and brought it to court was not objected to by Moss. Nor did Moss object to the testimony of Officer Caine of the crime laboratory when the officer stated that he had removed the envelope from the vault, took it to the crime laboratory for analysis, and then had replaced the package. Finally, no objection was made to the crucial testimony of Dr. Phillips, the police department's forensic chemist, when he stated that he had analyzed the contents of the initialed envelope brought to him by Officer Caine and had found that the cigarette package contained "Heroin, a derivative of Opium."
The courts of this State have repeatedly held that error may not be predicated on the admission of evidence unless there was timely and specific objection thereto in the trial court. Harrison v. State (1972), 258 Ind. 359, 281 N.E.2d 98; Gaynor v. State (1966), 247 Ind. 470, 217 N.E.2d 156; Winston v. State (1975), Ind. App., 332 N.E.2d 229; Mosby v. State (1975), Ind. App., 329 N.E.2d 600; Hardin v. State (1972), Ind. App., 287 N.E.2d 359. The fact that the alleged evidentiary error may be of constitutional dimensions does not alter application of this general rule. See Harrison v. State, supra; Tyler v. State (1968), 250 Ind. 419, 236 N.E.2d 815; Winston v. State, supra; Johnson v. State (1972), Ind. App., 281 N.E.2d 922.[1]
Professor McCormick states that:
"If the evidence is received without objection, it becomes part of the evidence in the case, and is usable as proof to the extent of the rational persuasive power it may have. The fact that it was inadmissible does not prevent its use as proof so far as it has probative value. The *144 incompetent evidence, unobjected to, may be relied on in argument, and alone or in part may support a verdict or finding. This principle is almost universally accepted, and it applies to any ground of incompetency under the exclusionary rules." McCormick, Evidence, 125-126 (2d Ed. 1972) (emphasis supplied).
That our courts adhere to this principle is not open to serious question. As stated in Norrington v. Smith (1972), Ind. App., 290 N.E.2d 60, 63:
"It is a well settled rule of law in Indiana, that where incompetent evidence, hearsay or otherwise, is admitted without objection its probative value is for the trier of fact to determine notwithstanding such evidence might have been excluded if proper and timely objection had been made. Kern v. State (1957), 237 Ind. 144, 144 N.E.2d 705; Chicago District, etc., Corp. v. Evans (1946), 117 Ind. App. 280, 69 N.E.2d 627; Klingler v. Ottinger (1939), 216 Ind. 9, 22 N.E.2d 805."
See also Indianapolis Blue Print & Mfg. Co. v. Kennedy (1939), 215 Ind. 409, 19 N.E.2d 554.
Relevant evidence, subject to exclusion on the basis of fourth amendment principles, which is admitted without objection is properly considered "to the extent of the rational persuasive power it may have", McCormick, supra, since the rationale behind the constitutional exclusionary rules, i.e., to deter unlawful police conduct,[2] does not address itself to the probative value of such evidence. Considering the above principles, even if the heroin was improperly seized so that it should have been excluded, and all testimony pertaining thereto would have been excludable on proper objection, Moss's failure to object to that testimony allowed the trial court to properly consider a substantial amount of highly relevant and probative evidence pointing to Moss's guilt.
To say that error in the admission of the heroin is not grounds for reversal is to say that such error, if any, is "harmless" in the context of this case. Since any error which might have occurred would violate one of Moss's federal constitutional rights, we are obliged to follow the harmless-constitutional-error rule formulated by the United States Supreme Court.
The original harmless-constitutional-error rule was announced in Chapman v. California (1967), 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705. It was therein stated: "that before a federal constitutional error can be held harmless, the court must be able to declare a belief that it was harmless beyond a reasonable doubt." Id. at 24, 87 S.Ct. at 828, 17 L.Ed.2d at 709. The Chapman rule was generally interpreted to mean "that the error to be harmless must not have contributed to the conviction." McCormick, supra, at 431; see also Traynor, The Riddle of Harmless Error, 44-45 (1970). It has been argued accordingly that a literal interpretation of the Chapman standard "would amount to an automatic reversal rule," McCormick, supra, at 431,[3] contrary to the rationale of the harmless error rule, i.e., "that efficient administration requires a fair but not perfect trial." 1 Weinstein & Berger, Evidence, p. 103-64 (1975) (emphasis supplied). We believe that it was in response to such an argument that the United States Supreme Court diluted the Chapman standard by adopting a more pragmatic approach to *145 harmless-constitutional-error in Harrington v. California (1969), 395 U.S. 250, 89 S.Ct. 1726, 23 L.Ed.2d 284.[4] In Harrington, supra, "the Court seems to have adopted the `overwhelming evidence' standard", McCormick, supra, at 432, which renders the error harmless if the amount and probative value of the other evidence in the record tending to sustain the finding of guilt is, when compared with the probative value of the inadmissable evidence, "overwhelming." See Note, Harmless Constitutional Error, supra, at 819.
As we have stated, the testimony concerning the heroin was properly admitted and entitled to its natural probative value. The testimony was uncontradicted and, if believed, established that the cigarette package found in Moss's possession contained heroin. The heroin itself would, in effect, be merely cumulative of the admitted testimony. In 1973, a unanimous United States Supreme Court stated that "[t]he testimony erroneously admitted was merely cumulative of other overwhelming and largely uncontroverted evidence properly before the jury," Brown v. United States, supra, at 231, 93 S.Ct. at 1570, 36 L.Ed.2d at 215, and that therefore constitutional error in the admission of the testimony was harmless. We think that the Supreme Court's holding in Brown, supra, is applicable to this case, and therefore conclude that any error which might have occurred in the admission of the heroin is harmless. See also Johnson v. State (1973), Ind. App., 299 N.E.2d 194, 199.

II
Moss's argument that there was insufficient evidence to sustain the conviction is without merit. As we have noted, there was testimony properly before the court which established that (1) Moss made a gesture as if to hide something between his legs when Officer Miller approached the car; (2) a cigarette package was found on the car seat where Moss had been sitting; (3) the cigarette package was held in an unbroken and unchallenged chain of custody from the time it was recovered to the time of trial; and (4) the cigarette package contained heroin. It is not for this court to disbelieve that testimony when the trial court did not. The testimony noted makes the facts of this case nearly identical to the facts extant in VonHauger v. State (1970), 254 Ind. 297, 258 N.E.2d 847 and Johnson v. State (1975), Ind. App., 325 N.E.2d 859, wherein the convictions for possession of illegal drugs were sustained. Even if the heroin itself had been excluded, since its admission is not essential for conviction (see Mayes v. State (1974), Ind. App., 318 N.E.2d 811; Winston v. State, supra), the testimony establishes sufficient facts to sustain the conviction. VonHauger v. State, supra; Johnson v. State, supra.
Affirmed.
WHITE, J., concurs.
BUCHANAN, J., concurs in result with separate opinion.
BUCHANAN, Judge (concurring).
I concur in the result only in this case because, in my opinion, the heroin was *146 properly seized pursuant to an investigative stop and search of the vehicle which was reasonable on the basis of facts known to the officer at that time ... relying on Luckett v. State (1972), 259 Ind. 174, 284 N.E.2d 738; Williams v. State (1973), Ind., 307 N.E.2d 457 and Elliott v. State (1974), Ind., 317 N.E.2d 173. Therefore, I would predicate the affirmance as to the admissibility of the heroin seized by the officer without necessarily relying on any other reason.
Correspondingly, I do not agree with the majority that "persuasive arguments could be framed for opposing views on the legality of the seizure ..." or any other inference that the heroin was improperly admitted into evidence.
NOTES
[1]  The admission of evidence "tainted" by its connection with an unlawful search and seizure is not "fundamental error" which this court will review despite the defendant's failure to properly object to its admission at trial. Winston v. State, supra.
[2]  See Mapp v. Ohio (1961), 367 U.S. 643, 81 S.Ct. 1684, 6 L.Ed.2d 1081; Elkins v. United States (1960), 364 U.S. 206, 80 S.Ct. 1437, 4 L.Ed.2d 1669; Weeks v. United States (1914), 232 U.S. 383, 34 S.Ct. 341, 58 L.Ed. 652.
[3]  See Note, Harmless Constitutional Error, 83 Harv.L.Rev. 814, 819 (1970).
[4]  The three dissenters in Harrington read the majority opinion as not merely diluting Chapman but effectively overruling it. Id. at 255, 89 S.Ct. at 1729, 23 L.Ed.2d at 288. The Harrington version of the rule has been implicitly reaffirmed by the Court in one of its most recent opinions on the subject; see Brown v. United States (1973), 411 U.S. 223, 231, 93 S.Ct. 1565, 1570, 36 L.Ed.2d 208, 215.
