Don Cameron, a former BART police sergeant and weapons expert who now teaches police officers about proper use of force, said Monday that he had watched footage of Grant's death and was convinced that the officer had meant to fire a Taser - a device that he said BART began using recently.
Footage taken from inside a BART car by a phone camera, first shown by KTVU television, shows officers forcing Grant to the ground and trying to hold him down. One officer appears to try to put cuffs on him before drawing his weapon and firing. In the video, Grant appears to struggle with the officers, though it is unclear exactly what he was doing.
Cameron said he made his conclusion based in part on the officer's stance, and the fact that a second officer moved away from Grant just before he was shot, perhaps trying to avoid a second-hand shock.
"If someone was actively resisting, which it appeared this guy was, the device to use would be the Taser, to overcome his resistance," Cameron said. "The Taser is a great controlling device. But if you grab the wrong device, you kill somebody."

damn this dood is so full of shit...you can see the other cop is still on him trying to detain him when he draws the gun...he still had a hand on him when the trigger was pulled im sure if he was going to taze him you would think he would have told the other officers to back up, you can see the other cop jump off at the very last second prolly cuz he didn't want no ricochet comin back at his ass, if not just a natural reaction to step the fuck back when steel pops off...looks like he still had a hand on him when the gun went off...mix up my ass that shit aint gon fly, his taser is on the front of his belt, his strap is on the side where every other police officer in uniform keeps it..
