Probably the same one. In the phone video, the cop did drop what looked like the taser beside the perp. I heard that some see taser wires connected to the perp as he was skidaddling.
Could be more to this story than what the dash cam or the guy with the phone cam caught. Maybe there was a confrontation not on one of the thus far shown tapes, but still this cop was in deep dodo for 8 shots to the back of a guy clearly running away, unless he was running to pick up a Tommy Gun out of view.
