Governor Jan Brewer signed a new gun law today, or maybe it was yesterday.
Since 2010 police departments in Arizona are prohibited from destroying guns they seize from criminals and are instead required to sell them to Federally Licensed gun dealers, who will presumably resell them to the public. The serial numbers of those guns then become legal again and like all guns legally sold by FFLs, are traceable to the legal buyer.
The new law signed by Governor Brewer extends this obligation to guns acquired in gun buy back programs. This is good. No gun should ever be destroyed. The gun never did anything wrong. It’s incapable of doing anything wrong. It’s just an inanimate piece of metal and plastic that may be used for good or ill. In that sense it’s no different from a baseball bat.
