So Richard Daley the Turd

is not only a nasty bastard, Chicago PD officers had no problem abusing people for him. Just wonderful.
When the audience started yelling questions, I raised my hand in an attempt to get called on. At that point a woman walked over to me and asked me if I was John Lott from the University of Chicago. I said that I was, and she informed me that I was not allowed to ask any questions -- no additional explanation was offered.

This appeared awfully strange, and it bothered me that someone would be singled out in the entire crowd. So after about 10 minutes, I decided to raise my hand again to ask a question. The same woman reappeared, this time signaling to two plainclothes men to come up behind me where I was seated. The woman stated that only the press were allowed to ask questions and that I would have to leave. While she was speaking to me, one of the men gave me a couple of solid hits in my back and then pushed me hard on my shoulder, almost knocking me out of my chair. I told her that I wasn't leaving, but that I wouldn't raise my hand again.

Some in the audience noticed. A reporter from the Baltimore Sun (Joe Mathews) had been seated next to me and gave me his card, stating that he thought the whole thing looked surprising.
