jeez, you have a severe case of paranoia if you wont sit down with out your back to the wall, im suprised you make it out of your own front door.Combat is all about psychology. Hell you yourself in another thread pointed that out when you referred to some "brain washed" soldiers sill freezing under fire. That is a psychological reaction to the fight or flight reflex.
Everything in the article is also NOT blatantly obvious. How many people, that you know, actively think about the preventative measures? Do they scan a room for entrances and exits as they enter? Do everything they can to have their back to a wall when they sit down? Do they practice what is often called target hardening?
