Who told you that your mother could go to jail for a year if some stupid shit kid trespasses onto your property, screws with your dog, and gets bitten as a result? Are you sure about that? If it's true, then Minnesota needs much better legislators. Did Al Franken propose that law? It's insane. You should call some lawyers and get to the bottom of it. In Mississippi, if that happened, the cop would go to the mother's house and tell her to keep her numb nut kid out of stranger's yards and not to let him screw with people's dogs. If the mother whined at the cop about how her son got bitten, the cop's response would be something like, "Uh, duh, YEAH!!! What the Hell else could have happened? "

If you find out with certainty that the law you mentioned is for real, call Bill O'Reilly about it. He loves to go off about stuff like that.
