I, too, am uneasy about some of the policies being carried out as far as the Guantanamo detainees are concerned, but the very fact that there IS so much concern about their status shows that we are a FAR cry from being a police state. Far more intrusive policies have been carried out in our history, and the histories of just about every nation. Rest assured, whenever any branch of government begins to get out of hand the others will soon rein it back in. That's our system of checks and balances at work.
However, the Guantanamo detainee situation is peanuts compared to the assault on the Constitution which was carried out by the Democrats, with Bush as an accomplice. That horrid campaign finance reform bill totally flouts the First Amendment and has far more serious ramifications than the abuses that may come of the USAPATRIOT Act.
