Most of these cold-blooded b**tards are already usually violating a multitude of laws and local ordinances, anyway. Stuff like: cruelty to animals, neglect, # of animals allowed per household, unlicenced animals, stray animals, etc.
I'm in total favor of hitting people with a felony if their dog mauls someone, like the new law taking effect in Dallas.
If the penalties are high enough (and enforced), it might go a long way towards cutting down on irresponsible jerks having vicious animals.
Fair enough ;)
