I spot a security breaches every time I fly. eg. People carry, pens, pencils, etc.
Anyone wearing socks or tights, is a risk. Take it off and get something small and heavy, you then have a deadly weapon. That is before I get on board.
After I board, and seated in 1st or business, if I'm lucky, then I am presented with quiet a few weapons, that would be taken off from me at security.
Shall I go on?
