Growing up in the streets of Los Angeles Marc "Animal" MacYoung learned a harsh - and usually ignored - reality about weapons. That is: you're more likely to be attacked by one than you are to attack with one. Being attacked by an improvised weapon is a game changer. It's not all about offense, you have stop the incoming attack, or you'll never get the chance to stop the attacker. This also means the mechanics of defense change drastically. An empty handed block against a tire iron will shatter your arm. You need an item to take that force instead of you.Pool Cues, Beer Bottles, and Baseball Bats is about how to use what's in your environment to defend yourself when you are attacked with a weapon.
