Bureau of Alcohol Tobacco Firearms Explosives

US Senator Dick Durbin is proposing a carrot-and-stick approach to encourage police departments in Illinois to trace guns used in crimes.

The Bureau of Alcohol, Tobacco, Firearms and Explosives runs the internet-based system known as eTrace, which can tell investigators who first purchased the gun and where it was manufactured.  But Durbin, a Democrat from Illinois, says just half of the police departments or sheriff’s offices in Illinois use the  system.
