"Chat-downs already are controversial in their trial stage. Civil-liberties advocates and some critics of the TSA see them as another government invasion of fliers' privacy, a hassle for mostly law-abiding passengers or ineffectual.

"They're asking questions that people have a right not to answer," says Mike German, senior policy counsel at the ACLU. "It's nobody's business — and certainly not the government's business — where you're traveling and why."
