Please reread my posts.
Never said anything about outlawing guns or even preventing people from having guns.  This guy was not an armed gun man, he was a drunk bum who probably didn't even know where he was.  Mace would have completely dominated him.
I think the problem is you guys have never been maced, I sprayed this bear mace and there was a very slight, almost undetectable breeze coming at me.  I puked and couldn't see for about 1/2 an hour.  It was horrible.
I am only suggesting that guns become a last resort.  If she would have seen a gun on the guy it would have been a different story.
So read my posts again 1) never said we should outlaw guns, just better control, penalties, and responsibility with them.  2) Escalation is pulling out the gun, this situation wen from a guy banging on her window and breaking it to her lighting him up with a shot gun.  Escalation.
(also in countries where guns are extremely well controlled the gun violence, even with criminals who by your logic should all be packing, is orders or magnitude less than the US.  Not saying we should do this, just something to think about.)
