So then if I go and grab jewelry from ajewelry store nobody can touch me????
They can touch you and more, but the law says they aren't supposed to shoot to kill you. Now if you were in England, they would be in trouble if they touched you.
If you were unarmed and running away I would hesitate to use deadly force on you, but there is a big difference between community service for stealing beer and 10 years for stealing valuables if you are caught, and I still believe in being judged by a jury over one guy. I guess it all depends on what you could sleep at night with, killing an unarmed man who stole a case of beer from me and posed no threat is over my own line I draw, you may be different.
I will agree that situations like this need to be dealt with, but allowing some store clerk the right to send a dozen shots down a street at the back of a fleeing drunk who never threatened him is going too far. Now had he caught up with him and kneecapped the guy with his Louisville Slugger on the other hand, I think I could sleep at night with that. :)
