Guns in two shootings came from Memphis police

Two guns used in high-profile shootings this year at the Pentagon and a Las Vegas courthouse both came from the same unlikely place: the police and court system of Memphis.
Law enforcement officials told The Associated Press that both guns were once seized in criminal cases in Memphis. The officials described how the weapons made their separate ways from an evidence vault to gun dealers and to the shooters.
The use of guns that were once in police custody to attack police officers highlights a little-known divide in gun policy in the U.S.: Many cities and states destroy guns gathered in criminal probes, but others sell or trade the weapons in order to get other guns or buy police equipment.
In fact, on the day of the Pentagon shooting, March 4, the Tennessee governor signed legislation revising state law on confiscated guns. Before, law enforcement agencies in the state had the option of destroying a gun. Under the new version, agencies can only destroy a gun if it’s inoperable or unsafe.
Kentucky has a similar law, but it’s not clear how many other states have laws specifically designed to promote the police sale or trade of confiscated weapons.
A nationwide review by The Associated Press in December found that over the previous two years, 24 states—mostly in the South and West, where gun-rights advocates are particularly strong—have passed 47 new laws loosening gun restrictions. Gun rights groups are making a greater effort to pass favorable legislation in state capitals.
