You consider what he was doing simply asking a question? He may have been
stating questions but he certainly wasn't asking them. He wasn't listening to a word Kerry was saying. In fact, he was talking right over him. The kid was causing a disruption. If I was in Kerry's place I would have had him escorted out. What is the point of listening to a fool that refuses to listen to you? Or for that matter even let you speak? He could have easily asked his questions and gotten answers. But that is not what he did and I don't believe that is what he wanted.
I don't think that is the issue here though. The police's use of excess force (in my opinion) is.
