If this had happened under GWB, I suspect that the people crying big-government foul would have applauded the TSA for cracking down on a traitor and demanded he be jailed for life as an enemy combatant.
Because you know, cognitive dissonance isn't actually painful. Which is a shame.
I won't get into the significant trust issues with sworn law enforcement doing **** like this (which he was, being a deputized air marshal and allowed to carry a weapon on a plane). There are better ways to whistle blow than randomly posting videos on Youtube. Ways that let you keep your badge and gun. Poor judgment from a person who is expected to exercise EXCELLENT judgment both behind the stick and behind the pistol.
Hell, Wikileaks is better than this approach.
