A guy in a tee shirt, shorts, with tattoos & an obvious attitude cuts you off, jumps out of his truck & is reaching in his back pocket for something, in the dark.
The immediate choice is this: If this guy is a real cop I might spend the night in jail, or if not, this guy is threatening to kill me & is likely reaching for a gun.
I’d have backed up, too, & probably kept going to the nearest uniformed police.
Whether he showed a badge or a tin fake would not have stopped me.
Is “I’ll blow a hole in your head” now the standard greeting from cops in a traffic stop?
Kinda scary, its very possible that when he started reaching for something I woulda shot him. If it were me in that circumstance.
