Cops that cover up murder are committing a serious crime. Nobody would take that risk. Nobody would put there family in that kind of risk. Risk jail to facilitate a coverup. Not happening.
You'd be surprised...they'd do it if they could get away with it...or if they have gotten away with cleaning up messes before. Afterall, it's just a dead black boy. Thousands of them die each yr, and nobody gives a fuck. Hey, he had a hoodie, well you know those types.
people in power and authority will do some strange shit, many times just because they can.
Until more info leaks out, this ain't looking too good. LE already have a tarnished image, if this is true, winning back the confidence of the community that they sworn to protect will be hard.
