Answer: He did not know he was being recorded. Not only that, but had he not been recorded he would (100%) have gotten away with what he did. The only reason anyone is talking about this is because some passerby recorded the incident, otherwise without that video that cop would definitely have gotten away with the shooting. A bit chilling to think of it that way - that the only reason he is even standing trial is because of pure bad luck for him in the form of a stranger with a cellphone camera, and that if that had not been the case, that the cop would be back on the beat.
This event happened back in April 2015. Who is talking about
it now? Has it gotten back on some appeals process?
