CNN has discovered that the TSA considers "complaining about TSA procedures" to be a profiling marker for potential terrorists. They explain that one terrorist (the "twentieth hijacker") complained a lot about TSA screening, and so that means "getting angry about TSA screening procedures" goes in the "signs of terrorist intent" bucket.
However, CNN also notes that intelligence analysts say that Al Qaeda official policy is for its operatives to be meekly cooperative when pulled over for TSA screening. Strangely, "cooperating with the TSA" has not been added to the TSA's profiling screen.
"Expressing your contempt about airport procedures — that's a First Amendment-protected right," said Michael German, a former FBI agent who now works as legal counsel for the American Civil Liberties Union. "We all have the right to express our views, and particularly in a situation where the government is demanding the ability to search you."
"It's circular reasoning where, you know, I'm going to ask someone to surrender their rights; if they refuse, that's evidence that I need to take their rights away from them. And it's simply inappropriate," he said.
