Without having all the details, which the video does not provide it is too hard to say. I will say once they told him to comply or he would be tasered and he didn't it is on him. My question here is why was he removed from the mic?  I support your right to free speech even if I don't like what your saying but, I do not have to give you a stage and a mic to speak from.Just my .02 on what I see here.
