Rand Paul "Detained" by TSA at Nashville Airport! What about Article I, Section 6? Did the TSA just trample on the Constitution?

“The Senators and Representatives…shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their Attendance at the Session of their respective Houses, and in going to and returning from the same….” according to Article I, Section 6.

TSA Tramples on Counstitution! This should get interesting! Any ideas on how this will play out in future Senate funding hearings and bills brought before the Senate re TSA?
