Hear me out. Has any crime, anywhere, ever been solved by tracing a gun’s serial number? I don’t know of any. In the Hollywood version, a policeman finds a gun near a crime scene, traces the gun, and goes and arrests the person at home. In reality, that never happens, they either have the gun and the perp at the same time or never recover the gun. In the very rare instances where they have a gun and no suspect, a gun trace leads to someone who had their gun stolen or goes nowhere. So I am again: Has any crime, anywhere, ever been solved by tracing a gun’s serial number?
