There is only one type of security to use - PROFILE! Look ‘em in the eye, question ‘em, ask them questions and if they fit the profile grill ‘em. I just went through Boston last month and I took off my sport coat and got yelled at. I wanted to put it in a gray tray. He asked me ‘why? YOU DON’T NEED TO TAKE YOUR COAT OFF!’ I have 2,000,000 frequent flier miles in my account and I have to deal with this big jerk. Sorry, every airport in America I have traveled in I have taken off my coat even with my TSA Precheck because I put my wallet and passport in it.
Ah, the El Al method.
When was the last time a muslim terrorist took down an El Al flight?
