If you train an animal to attack, and then it attacks, then you did intend for it to do harm.
I read above the definition of 2nd degree murder, and it specifically uses the word ‘causes’. So, the law is saying that there is something beyond criminal negligence that isn’t you pulling the trigger, but does allow for you to be the ‘cause’.
What you say about criminal negligence I agree with. What the law tries to distinguish is not someone who ignored something they shouldn’t have ignored, but who also established a situation that would have reasonably led to the death of another person.
Great, so all the people doing Schutzhund with their German Shepherds and Belgian Malinois are now automatically guilty? No, those dogs are truly trained for specific actions to be under control, whereas trailer-trash junkyard-dog pit owners are at best conditioning dogs to just plain act mean and vicious, albeit they already have bred-in tendencies.
Guys like this are not model citizens, but they are not necessarily guilty of out and out murder, even if the law has been twisted to get more ridiculous (as if that hasn’t happened before).
