Claiming this is a hit and run is purely speculation on your part. I'm sure it justifies him getting shot four times.Off Duty, out of uniform.
Backed into a guy's motorcycle, got into a dispute, tried to leave (hit and run?), biker shot him.
Hardly worthy of note.
You would shoot somebody over a property damage accident only? The bikers membership goes to his state of mind. Would he have shot if he knew it was a police officer? Or did he think it was OK because it was a "civilian"?Causing an accident and driving away without trading information isn't Hit and Run?
How is the biker's membership in a bike club relevant?
