This administration knows how to detain people.
That said I can kind of see the rationale. You have here a huge disaster and a ton of people who are going to get lots of aid. There are lots of people who weren't in the disaster who might want on the gravy train, and they are trying to keep them out.
But still I can't help wondering what their biggest fear here might be. Could it be that actual Katrina survivors will get real jobs and integrate themselves into other communities? As boxley could easily point out, this wouldn't be the first time that the Federal government has forced large groups of people to become needy so that the government can then feel justified in having a bureaucracy built around providing for their needs.
Cheers,
