If I accept your 2% bad cop number, and I will, then perhaps you can explain to me why the other 98% of good cops don't turn them in? Why the KKK members of our local police safely continued in their jobs, why no cops see anything worth reporting so often. Why the officers second to the scene stay silent when they know damn well what really happened. When they cover each others butts rather than protect and serve. If those 98% of good cops would turn in the 2% of bad cops, not just the killers, but the cops who joke about hassling black motorists, about trading sexual favors with hookers for non-arrests, who they know are on the take from criminals. As Sir Thomas More explained, Silence betokens Consent.
