Ex-wife No. 2 used to say, “hesitation kills.” It’s a riff on the old adage “he who hesitates is lost.” Sam’s take was more direct. More effective. Especially when it comes to ending a violent attack. Failing to mount a sufficiently quick and violent counterattack against those who would do you harm could well be the last mistake you ever make. Simply put, speed, surprise and violence of action is the secret sauce. Guns are a genuine boon in that effort. But don’t get to thinking a gun is a magic talisman. It’s a tool. A part of a plan, not the plan itself. If you don’t know what I mean, if you want to see what happens next, make the jump for the autoplay video . . .
