Tuesday: I doubt in that situation tasing was an option as it happened so quickly. He save the life of another black girl which is ironic and it’s own way because Black Lives Matter are still protesting his actions. Had he done nothing or had he acted too Late, and the other black was killed by the knife wielding girl, he would be criticized for not having done some thing. It’s a lose lose for cops. That’s just my opinion of course but it seems like they can’t win when they are faced with a split second decision. I doubt that cop woke up that morning and thought “I think I’ll kill a black girl today.”
