From an article on the database that stores information on the habits of people who travel (like what books they're reading, who they travel with, where they're staying and so on.) A database that started, of course, with Clinton (like the no-fly list) but has become much worse under Bush.

Zakariya Reed, a Toledo firefighter, said in an interview that he has been detained at least seven times at the Michigan border since fall 2006. Twice, he said, he was questioned by border officials about "politically charged" opinion pieces he had published in his local newspaper. The essays were critical of U.S. policy in the Middle East, he said. Once, during a secondary interview, he said, "they had them printed out on the table in front of me."
