The dead guy being identified as a "by stander" was in the dark colored 4 door car parked at an angle in the right hand lanes toward the end of this video. It looks like a typical unmarked detectives car but it's not. It's a full size Lincoln, it's appearance could be why he was shot at by the bad guys.
The UPS driver is the one on the ground getting all the attention, the cops knew they f'ed up.
