It is not the dogs fault, it is the father/policeman. Had the dog been properly stored and taken care of the incident would not happen. Just like gun incidents, the guns should not be blamed, neither should the dog. There needs to be serious repercussions for doing something as stupid as this guy did. There is no doubt a non LEO would be prosecuted, whether gun, or dog.
I believe the father should be fired, prosecuted, and the child removed from his care. He is reckless stupid man, hopefully his wife leaves him and takes the child for the child's safety.
