Today’s New York Post provides more detail on where accused cop-killer Dexter Bostic got the gun used to murder Police Officer Russel Timoshenko.

Dexter Bostic allegedly used a .45-caliber Llama on July 9 to fire two shots into Timoshenko’s head. The young cop died five days later.

That high-powered handgun came from R&B Guns in Hampton, Va., Brooklyn DA Charles Hynes said yesterday.

It was bought in August 1999 by a man who has since died. His family is cooperating with the feds.

Guns involved in more than 1,000 crimes have been traced to R&B Guns between 1996 and 2000, according to the Brady Campaign to Prevent Gun Violence.

It is vitally important that we continue to ask the source of guns used in crimes. The more we learn about the black market in guns, the better our law enforcement agencies will be able to deal with the dangers enhanced by gun traffickers. Knowing where crime guns come from can expose crime patterns, and help shut off sources of crime guns.

Law-abiding gun owners should not be confused into supporting law-breaking gun traffickers. Those who’ve been able to create a smokescreen around the issue help protect the dealers who help fuel the violence in our communities.
