The long lines are what they are bombing now, terrorists targeting airports right now are thinking that rolling up with a suitcase filled with explosives in the middle of a large crowd waiting for security:
a) Shuts down the whole airport.
b) Inflicts more causalities than randomly crashing an airliner
c) Will make security spend massive amounts of money countering
Let''s review, TSA has made us less safe by offering us up as a larger and slower target. It is like putting security at the watering hole to make sure no one is a crocodile while lions eat everyone else who is waiting in line.
