Whatever. I don't see what one has to do with the other. Even if we assume all criminals have firearms or no criminals have firearms, what does that have to do with arming the citizenry?
A community or a city may believe that unarmed citizens are actually safer when facing an armed criminal. Shouldn't they have the right to implement that (assuming, of course, their state constitution allows that)? I didn't realize the constitution was a check on stupidity.
