Nazi's cooked people in giant ovens.
Red Herring.
Only a tiny minority did. And the point is, it's the culture that counts. Nobody cares that there are good police on the job, when there are police abusing their powers, murdering citizens, using brutality and violence to deal with peaceful demonstrators, using their power to endorse corruption etc etc. The nature of the work means they all should be good. If the Police as a whole refuse to eliminate corruption and police abusing their powers they will continue to be distrusted and despised by the public. Same goes with Islam, if the moderates can't reel in the extremists, they too will continue to be mistrusted and despised. Nobody cares about the peaceful within a group, it's the violent and corrupt that control the agenda. The current solution is to scapegoat individuals, which is a classic way of avoiding responsibility and the problem persisting.
