Where is the arrest of these cops by good cops?? Huh? Where???
Excuse me, but that's a little bit like expecting "good Muslims" to engage and stop the murder, detonative savagery and rape committed by their "extremist" cousins.
Both approaches of hoping for self-policing are really expecting the enemy to lose to you on purpose.
I expect you know this, and I am not lecturing - merely adding $.02 to the mix.
