When you have weapon that’s incredibly powerful, no one wants to fight because the costs of fighting are so high. But why is it in the context of guns we don’t think of guns as deterrents, we think about guns as, being this, causing the violence... in the old days in the fifties and sixties when there weren’t that many guns around, disputes would be solved with fist fights or maybe with knives, okay. And the thing is, look when you fight someone who’s much bigger and stronger than you, you know who’s going to win. And if you already know who’s going to win you don't need to fight, because if you know you’re going to lose, why bother? ... guns really destroy that order because anybody with a gun can beat anybody without a gun, right? It doesn’t matter how strong you are or whether you’re popular or unpopular. The gun basically makes it so that uncertainty of the outcome of the fight is immense. And then that actually has the opposite effect of deterrents, because now if anybody can win the fight there can be more fights, because it’s not like you’ve got a certain winner and certain loser, which means you don't have to fight in the first place. And I think that’s a really powerful idea.
