was Bonny of "bonny and clyde" killed while urinating?

So called because of it's short barrel. It has nothing to do with a squating position, it's a refence to barrel length. Haven't you ever heard the term squat-nosed revolver? It's refers to revolvers with really short barrels that are easy to conceal from a casual inspection. And Bonnie's "squat gun, was found still strapped to her leg when the bodies were removed from the car.

No,the posse ambushed their car as they were driving down a dirt road. Bonnie was sitting in the front passenger seat and slumped over in the seat after being shot and killed. She had .38 Colt revolver taped to her thigh, that's the gun they called the "squat gun."

First source shows her position in the car when she was killed.
