And therein lies my problem with body & dash cameras. Perception is reality and the human eye doesn't see everything a camera does nor does it experience emotion, problems with depth perception, does not detect the direction of sound, doesn't take in to account prior experiences with certain people, etc.. Video quite frequently provides those sitting in judgement with one whole hell of a lot more information than an officer has in the moment and they don't have to make their decisions with the type of stresses believing you might die tend to put on you.
Where do you draw the line on such things? Do you create a standard, or do you rely in each officer's individual opinion? I not sure how many, but I think they said 8 other officers were on scene, and yet none engaged the suspect. One officer went on record in stating how he didn't view the suspect as an immediate threat when he was shot. The officer that killed the suspect, said that he lunged at him. In his mind, maybe he did, but the tape tells a different story. He shot the guy, the guy falls down, and he continues to unload into the guy. Unfortunately for the officer, we have the luxury of Monday morning QB-ing because we have the video... but even so, despite tunnel vision, his eyes surely were working well enough to see the guy fall, the mind sound enough (for most) to recognize the threat was over, and yet he continued to empty his mag into the guy. In light of such, I can't reconcile why so many think he's getting railroaded. Well, I can, but that's another conversation.
