If the good cops don’t finally rat out the bad ones, how does it even MATTER that there are “good ones”...?

"If the good cops don’t finally rat out the bad ones, how does it even MATTER that there are “good ones”...?"

If a "Good" cop becomes aware of crime committed by a "Bad" cop and doesn't report it, he becomes an accessory after the fact and is considered just as guilty as the "Bad" cop. Therefore, he becomes a "Bad" cop too, and the swamp will soon need to be drained.

You’re so correct.
