when he said he was there to "point out agitators". Also, I think that statement outs himself as a liar because right before he had just said that, he said he wasn't there to infiltrate. Well if you're there to gather information on who the agitators are, then, you are there to infiltrate. So no surprise to me, just another lying cop.
