My favorite "gangsta" story is from there in The Alamo City. = A 17YO (who had a long string of criminal offenses, back to his 9th year) & wearing this pants down about 6-12" below his underwear, entered a Valero, approached the clerk on duty, told her that this is a stick-up, received about 30.oo in small bills & change. When some customer yelled, "Here comes the cops!" the thug turned run out of the store. At that point, his pants fell down, tangling his feet up. He fell headfirst into the glass door & knocked himself out cold. - A few seconds later, the SAPD arrived, found the thug "knocked out cold", handcuffed him & took him to jail.
(I heard that when the story "came out" at the city jail, that even other prisoners were laughing AT the "would be crook".)
You won't believe this one but it really happened. Two local criminal masterminds decided they would rob this credit union, so in they went. One small problem it was an administrative office, just paperwork no cash. When they demanded money the credit union people offered to give them a check telling them it could be cashed at a check cashing business across town. "Yeah okay man we'll take a check." So they did, the cops were waiting at the check cashing place and sure enough they showed to cash their check.
Believe it or not a "would be bank robber" in VA some years ago (when I was stationed up there) went into a VA Commerce Bank branch, handed a teller a note that said, "Give me the cash & call nobody or you be dead, B----."
(She obediently filled his plastic bag with money & the robber fled.)
When he returned home a hour of so later (He had stopped for beer & other things at Safeway, before driving home.), he was arrested by the VASP in his own driveway. - Turns out that he had written his note on the back of a blank check, that had his name/address printed on it.
("Really brainy" was that clown.)
