What about U.S. citizens? If a citizen is determined to be in the company of known terrorists who otherwise would qualify for ruthless military attack due to their plotting our destruction, then detaining him seems prudent ("the Constitution is not a suicide pact," etc.)
But we should not kid ourselves -- this is what dictators always claim as well. THE difference is precisely the American culture of vigorous, democratic debate. In other words, this is being done correctly -- the Bush administration did not detain this guy in secret. The political process and public opinion counts in this country. A president rounding up political enemies and claiming they are terrorists would not work here. If that ever changes, hopefully there would be a backlash and the courts, Congress, and people would intervene in time. American dictatorship is less a threat than American suicide by political correctness, at least today.
you have made a very good point, although I am concerned about the doors this sort of thing could open, the fact that this is a PUBLIC event garners a gold star for GW
I do think, however, that we need to try people like this dirty bomber and the Marin county guy for TREASON. It seems to me that "aiding and abetting" enemies of the United States shouldn't be difficult to prove.
