In a display of just how horrific federal agencies can use the Anti Terror laws etc. to bully or harass people of a different opinion you should read;
Another Hacker’s Laptop, Cellphones Searched at Border

The sum of the article is that known and respected computer-security researcher Moxie Marlinspike was detained by federal authorities for 4½ hour when reentering USA, his equipment was confiscated and possibly cloned (returned to him afterwards), all because his name has made it to a federal watch list.
