After passengers reported the suspicious behavior of six Muslim clerics on a US Airways flight last November, the clerics were questioned and cleared--and the passengers were slapped with a lawsuit. The Council on American-Islamic Relations has helped the "flying imams" file an accusation that the airline and the passengers engaged in a "malicious ... conspiracy to discriminate" against them. Rep. Peter King, the New York Republican, is sponsoring an amendment to offer legal protection to anyone who reports suspicious behavior in good faith. The House has passed it 304-21, but most Democrats in both chambers opposed it, and their leaders had to be pressured into letting it stay in the homeland-security bill. Passenger vigilance is an essential component of our post-9/11 security procedures. Political correctness, backed by legal intimidation, should not be allowed to weaken that vigilance.
