Again, a quaint analogy - this one appears to allude to shootouts outside the ol' saloon, perhaps in front of the half constructed clock tower, whilst the sheriff is incapacitated?
I'd be genuinely interested as to how often the law abiding citizens use those guns to defend themselves successfully. The very fact that there are potentially guns on both sides escalates the risk for BOTH parties.
Also, reduce the legal guns and you'll reduce the illegal arms too.
