Trouble at the Astrodome?

Last night we got a bunch of calls from disgruntled evacuees at the Astrodome who were extremely upset at their treatment in Houston. They are saying that police are arresting them for the most minor of infractions and refusing them to do simple things like wear their shirts on their head to protect from heat (probably in fear of some sort of gang symbolism). While on the phone, other volunteers here said that they could hear "lots of people yelling in the background" this morning. There's no information about troubles there in the Houston Chronicle.

We were told by one person that they were loaded on busses to take them to sign up for new housing in Houston only to be left in a strange area while the busses left them alone. That's not the sort of mistake that should be made two weeks after the evacuation.

General unrest is to be expect at this point, but if you've been in the Astrodome in the last 24 hours, please feel free to leave a comment appraising me of the situation.
