Guns used to prevent "gun violence" - well, sorta...
Happened in Dodge City. "One afternoon a cowboy rode into town, tied his pony at the hitchrack in front of Wright and Beverley's store, and with his pistol in its holster, jingled his spurs down the rough broadwalk toward the nearest saloon.
Marshal Wyatt Earp stopped him. 'Carrying firearms is not allowed in Dodge. You'll have to check your gun.'
The Texan drawled, 'Who's goin' to make me?' and reached for his weapon.
Wyatt did not reply. Swiftly he buffaloed the saucy stranger, laying down the long barrel of his Buntline Special smartly against the man's temple, just under the hat brim. Down went the cowboy, as if he had been poleaxed, and later, in the words of the old song, woke up broken-hearted in the old Dodge City jail..."
Was told there was a Fremont cop of Chinese descent back in the 1980s. He carried a 6" magnum. He liked the heavier barrel not because of increased velocity or longer sight radius, but because he'd bludgeon the bad guy over the noggin with it. Never met the man msyelf and don't know if he still does it. Law enforcement from the 1880s to the 1980s had some things in common.
