From WeaponsMan:
If you’re not paranoid about a training gun that looks and feels like your service firearm, if you’re not constantly checking and double-checking, and if you’re not still observing the three most fundamental rules even when you know the training aid can’t possibly hurt anybody, well, then the difference between your situation and the much less enviable one in which Lee Coel finds himself is not dependent on anything but happenstance, chance, fortune… luck…
