I saw a guard slashed 500 stiches with an exacto knife before he knew what hit him and also an inmate with his throat cut to the bone with a single edged razor blade. the 21-foot rule is for real in knife attacks.
At 21 feet you prefer the killer have a gun aimed at you rather than holding a razor knife?
I don’t.
Your examples of knife wounds in surprise attacks, or any other attack ,do not make them better than a gun, would those surprised victims be better off having a pistol shoved up against their bodies and the magazine emptied into them?
