So a left-leaning pro-gun control commentator watches a video of a courageous commuter tackling an armed robber and advises viewers “don’t try this at home kids I’m telling you you’re going to get shot.” Whether or not you think that’s wise counsel isn’t really the point. This kind of armed encounter involves so many variables it’s impossible to play ‘parse the pistol.’ But one thing’s for sure: if you’re going to attack your attacker, do so with as much force as you can possibly muster. Go all in as quickly and violently as you possibly can. No holds barred. (Forget the friggin’ iPod.) It’s that aspect of Krav Maga, rather than any trick techniques, that makes it such an effective method of self-defense. But you don’t have to master it to use it.
