We'll take a hard look at a series of security policies enacted since 9/11 and the ways in which they erode civil liberties. We'll talk with Saadiq Long, a U.S. Air Force Veteran who has not been allowed to board a flight to return home to Qatar, to learn how these otherwise invisible security policies affect the people targeted by them.

Joining Chris on Sunday at 8 AM ET on MSNBC will be:

Gadeir Abbas, staff attorney for the Council on American-Islamic Relations (CAIR).

Saadiq Long, U.S. Air Force veteran who was barred from boarding a flight from Oklahoma to Qatar.
