Here is a short video made to raise awareness of terrorism threats and what you should do in the event of such threat. It also subliminally tells you to give up your rights at TSA checkpoints.
If you see suspicious behavior - make the call.
Extra fun fact in the USA you have an 8x higher chance of being killed by a police officer than a terrorist. Maybe more in NYC or LA.
Girl terrorist is a super hottie, I'd let her hijack me any day :)
