Let's concentrate on Criminals and the certain threat they are to innocent people...not the law-enforcement heros that protect law abiding citizens.
In my town in 2004 about 25% of the police force was under investigation or already jailed on various corruption charges , generally abuse of office , stealing drugs from pushers to resell themselves and things like that .. this is Apopka FL ,, I personally ran pirate satellite TV hookups for half the force .. They were to a man power junkies ... my home was raided on a "quick knock" in 1998 when I was at work due to a bad address/phone number association in the 911 system, they scared my wife half to death.. If I was home there would have been bodies ,, I GUARANTEE IT ... anyone busting in is a target ,, anyone can yell "police" and I don't care they're going down, this sort of thing happens every day because of the mentality that goes into being a SWAT team member and because they feel they need to earn their pay by being brutes, I wouldn't be surprised if this wasn't at least 5X more common than is reported.
