Security Theater at Gatwick Airport

This is theater with very expensive tickets. At first I could not believe that people are really that dumb to believe that any of this buys us any security but talking to a few people in line I found that most people agreed that this must be done to ensure a safe flight.... Am I wrong I wrong on thinking this all is a load of bull? Our so called terrorists must be laughing their asses off.
