CLARK
v.
The STATE.
No. A07A0134.
Court of Appeals of Georgia.
April 27, 2007.
*672 Mark Benjamin Beberman, for Appellant.
William Steven Askew, Dist. Atty., Mary Kathryn Mitchell, Asst. Dist. Atty., for Appellee.
MIKELL, Judge.
Following a jury trial, Robert Lee Clark, Jr., was convicted of two counts of selling cocaine, OCGA § 16-13-30(b), and sentenced to concurrent sentences of fifteen years on each count, with ten years to be served and the balance on probation. He appeals from the denial of his motion for new trial, contending that the evidence is insufficient to support his convictions, and that the trial court erred (1) in allowing the state to comment during opening and closing arguments on the connection between illegal drugs and crime in the community; (2) in admitting his booking photograph into evidence; and (3) in permitting the state to elicit testimony from eyewitnesses concerning the level of certainty in their identifications. We affirm.

*673 On appeal from a criminal conviction, the defendant no longer enjoys a presumption of innocence, and the appellate court views the evidence in the light most favorable to the verdict. We do not weigh the evidence or determine witness credibility. As long as there is some competent evidence, even though contradicted, from which a rational trier of fact could have found the defendant guilty beyond a reasonable doubt, we must affirm the judgment on the jury's verdict.[1]
So construed, the evidence shows that while working in an undercover capacity, GBI Special Agent Paul Smith of the East Central Georgia Drug Task Force, accompanied by confidential informant Shawn White, twice purchased cocaine from Clark on November 5, 2002. A forensic chemist from the state crime lab confirmed that the substances sold were cocaine, weighing less than one gram. The state also introduced into evidence and played for the jury the surveillance videotapes of each transaction, still photographs taken from the videotaped transactions, and a booking photograph of Clark. Both Smith and White identified Clark at trial as the individual who sold them the cocaine.
GBI Agent Travis Akridge, who had been providing backup to Smith during the undercover operation, reviewed the videotape shortly after the transactions and identified Clark. Akridge explained that he went to school with Clark and recognized him from an old yearbook picture. At trial, Akridge identified Clark as the individual in the videotape. An arrest warrant was issued for Clark in February 2004.
1. We first address Clark's contention that the evidence was insufficient to support his convictions. While Clark enumerates this alleged error and cites the proper standard of review, he provides no argument, citation of authority, or citations to the record to support his position. While Clark has abandoned this enumeration of error under Court of Appeals Rule 25(c)(2), we have nonetheless reviewed the record and find sufficient evidence to authorize the convictions. The jury observed the transactions on videotape and two eyewitnesses identified Clark.[2] Accordingly, this enumeration of error is without merit.
2. Clark contends he is entitled to a new trial because the state improperly commented during open and closing arguments on the connection between illegal drugs and crime in the community. During open arguments, the state made the following comments over objection:
Our lives now in a lot of ways are controlled by what happens in the drug world because a lot of our crimes that happen today are related to drugs. . . . And many of the crimes that we deal with are connected to drugs, even crimes such as burglaries, armed robberies, forgeries, they're all connected to this world that you're going to hear about today.
During closing, the state again argued, over objection,
[a]s I told you in my opening, drugs lead to more crimes, and I'm sure you've heard that on television again and again. Burglaries . . . [t]hey do lead to other crimes, other crimes that have victims, other crimes that can really have an impact on people's lives, and have an impact on a community like Emanuel County.
Though it is improper for the state to comment on a defendant's future dangerousness, it is not improper for the state to appeal to the jury to convict for the safety of the community or to curb an epidemic of violence in the community.[3] Nor is it improper for the prosecutor to emphasize to the jury its responsibility to enforce the law.[4]*674 The state's argument in this case was not improper.
3. Clark next claims the trial court erred in admitting the booking photograph into evidence because it improperly placed his character in issue by showing him wearing a Department of Corrections uniform. After the state questioned Smith about the still photographs, the following colloquy ensued:
[STATE]: [D]id you also obtain an arrest booking photo of the defendant?
[SMITH]: Yes, ma'am, I did.
[STATE]: For purposes of trial today.
[SMITH]: Yes, ma'am, I did.
Clark objected to admission of the photograph into evidence, arguing that it impermissibly placed his character in issue. The state countered that it was relevant for purposes of identification. The trial court overruled the objection.
It is well settled that mere admission into evidence of a "mug shot" of the defendant does not indicate that the defendant was guilty of any previous crime and does not place his character in issue.[5] Neither does reference to such a photograph impermissibly place a defendant's character in issue.[6] The photograph shows only the collar of Clark's uniform and does not suggest that he had been the subject of prior arrests or convictions for other offenses.[7] Moreover, the jury could not figure out from Smith's testimony whether the photograph was related to this offense or a previous arrest.[8] As the booking photograph in no way suggested that Clark was guilty of any previous crimes, the trial court did not abuse its discretion in admitting it.
4. Relying on Brodes v. State,[9] Clark argues that the trial court erred in allowing the state to elicit testimony from Smith and White concerning the level of certainty in their identifications. We find no abuse of discretion. In Brodes, our Supreme Court held that it could "no longer endorse an instruction authorizing jurors to consider the witness's certainty in his/her identification as a factor to be used in deciding the reliability of that identification[,]" and advised trial courts to refrain from giving the "level of certainty" instruction to jurors.[10] The Brodes decision does not, however, prohibit an identification witness from testifying about his or her level of certainty, or restrict the state from inquiring about the same. As we noted in Best v. State,[11] a defendant can challenge such testimony through cross-examination, expert testimony, or the presentation of testimony from other eyewitnesses.[12]
Judgment affirmed.
JOHNSON, P.J., and PHIPPS, J., concur.
