Bill's on my twitlist, so tell him for me that to see a person stand up for himself where the cops can't is A Good Thing. It is the type of people upon whom this country was founded. While I agree that it's sad that the perp was so drawn, it's good that the shop owner stopped him cold, with whatever means necessary. He's reacting to reality, not some ideal. Have Bill work his ideal on the -perps-, not us. If violence is so bad, if Bill had been there, would he have tried to prevent the shop owner from stopping the truly violent person in that store? Would he have gone after the perp empty handed? Feh!
That was purely self defense and defense of his other clients by the shop owner. The cops are surely calling it a righteous shoot.
