A dog may chase a student for two reasons: the dog is displaying play behavior or the dog is displaying aggressive behavior. Chasing is not de facto aggressive behavior for a dog.
Evidence of the dog’s aggression has not been produced.
You are not entitled to any “evidence” of anything. In fact, you are assuming facts not in evidence, because of your desire to either attack the police, or worship a dog. I’d kill any dog that I deem to be acting aggressively toward me or another human being. People need to control their animals. Animals are subject to the dominion of humans. Such is the created order.
Thunder went to k-9 training in new york and passed the course and was put on the force in new jersey he was let go due to he wouldnt bite a suspect but to find drugs Thunder was good at it..when thunder was let go due to not attacking our family got him.
If true, I would imagine that the police in New York have, or had, records on Thunder including the grounds for which he was retired.
That would be excellent evidence to help determine one way or another the truth of the matter.
Video of the shooting would be informative as well. No one has yet posted any video of the incident anywhere that I could find (and one would suppose that one or more of the students would be filming the incident on their phone cameras.) If video appears, we shall see what it reveals.
