It's always an arbitrary time limit, which they don't adhere to, and then they block egress, after they tell you which way to go.

I once went to protest Bush at the retreat in No Cal, and the cameras were rolling. They wanted to know who we were like we some group of spies or something, instead of a bunch of hippie libs from SF, protesting war and policies. It was deep with men behind mirror shades. I think we were out-numbered.
Seriously, this is not just looking for the criminal element. They are engaged in something far more sinister. They probably have certain people they are looking for as well.
