Believe me, a bottle, a hammer, anything solid in the hands of an enraged person can kill, and a lot quieter than a gun.Some people aren't unused to the mind-numbing blast of ear-ringing sound, the intense flash of light and smoke even a single shot produces, but most people don't fire their weapons that often.And a shot person is very messy...I once fired my .45 auto accidently in my living room...long story, but it was pointed safely while I handled it.I was deaf for a few minutes, then my ears were ringing for quite a while. I was semi-stunned from one closed room shot.
A good argument for getting a suppressor|silencer|can. The reasons for making something that actually makes a gun safer a class III purchase and illegal in some states just doesn't add up. One of the many legal aspects of guns that seems based on Hollywood demonization of guns.
Lack of education is the biggest enemy of guns and RKBA.
