Imagine for a moment that it’s the middle of the night and you’re sound asleep in your bed. All of a sudden you wake up to the sound of breaking glass and voices coming from down stairs. You’re groggy and tired but decide to go investigate. As you come down stairs and round the corner you find yourself face-to-face with two guys in dark hoodies. They have crowbars in their hands and suddenly you realize there is another guy coming up behind you. You have just walked into an ambush.
