The speed of attacks is a thing that we see over and over again. It’s impossible for you to be all-knowing of the things that are happening around you at all times, and that’s a little frustrating. Mostly, it’s frustrating because we don’t get to choose when the bad guy will strike, which creates the need to pay attention to others.
In the video below, a very quick attack –with little indication that an attack is about to take place– nearly kills an armed border guard.
Had the guard not been armed and able to fire his gun, the attack could have continued and he ma not have made it.
