If the kid jumped off a bridge would you blame the bridge? Any teen knows a fence is there to keep him out. Give him a Darwin award and move on.
If the dogs get loose or a small child gets mauled, that's on the owner for being irresponsible.
As I said in my OP, should it be tantamount to a death sentence for jumping a fence into someone's backyard? Look, I get that the kid was in the wrong, but I disagree that he deserved to be mauled to death. Obviously, most here don't share my view.
holding up a liquor store with a handgun usually isn't a death sentence either if the person is convicted, however a person has a right to use deadly force to protect themselves in threatening situations, and the burden of proof of "threatening" usually isn't that high.
The kid put his life into his own hands going into a yard, more so if it was a yard with dogs in it.
