Air travel security stupidity

So some jackass tried to blow up a plane during the last hour of flight as it was in-bound to Detroit from Amsterdam on Jesus' birthday.  And what did da Gubment do in response?  What it does best: It overreacted.

This time the TSA has decided that air security will be "unpredictable".  That is, there will be different restrictions in place at different airports.  Several of these "unpredictabilities" (if that is a word? ... another wordicle!) include only allowing each passenger a single carry-on bag (therefore more moola for the airlines in the form of additional checked bags that we get to pay for), not allowing anyone out of their seat during the last hour of flight (i.e. no potty breaks --- Clamp it off!  CLAMP IT OFF!!!!), not allowing any passengers to have anything on their laps during the last hour of flight (oh for those of us with kids --- that'll be fun), and leaving the cabin lights on during take off and landing (uh ... just not sure what sort of sarcasm to inject for this one since it kinda stands on its own in the land of the stupid).
