Looking at this from an other angle, what happens if one of these state and local cops gets co-opted by the jihadists? Say one has a gambling problem and amasses debts. A Moslem buys the juice and then deals to get the compromised cop to take articles on board.
Homeland Security should look into this. There are plenty of examples where cops are led astray and the safety of our airplanes is too important to allow every single cop from every juristiction unimpeded access to airplanes.
State and local officers need to be flying at the request of their agency. In other words, it has to be work related, and it will require their superiors to sign off on their trip.
What happens if one of these cops IS a muslim, doesn’t hide it, then carries a gun onto a plane.
Remember Ft. Hood anyone?
