So what on earth happened, or seem to.
Was it like the cop just snapped? Flashback to a combat situation, then shot on autopilot as it were? Maybe it will be an insanity defense situation.
He fired into the back of a fleeing car.
If the driver is fleeing in your direction, a cop is free to fire. Leaving and driving away? Nope. Can’t fire.
Then the cop lied. Cop dash cams caught him lying. As well as other cops on the scene who would not/could not aid in his lies.
