Quote: "If you cannot hit what you need to hit, as many times as necessary, there’s little point in carrying your gun. It’s not some sort of magical talisman that wards off evil-doers by its mere presence. It is only through the skilled application of the weapon that it becomes effective. That requires training, but more importantly, it requires continuing practice of the skills learned in training."
