I can't decide which is worse:
Two or three cops lay a whoopin' on a protester
Dozens of other cops who engage in a criminal conspiracy to look the other way, refuse to testify, or taint their evidence to ensure their brutal colleagues are not caught or punished.
Any honest cop who comes forward and braves the inevitable 'shunning' should be nominated for Police Officer of the Year and put in a witness protection programme.
Only a few bad apples. And the other 95% will cover-up for them. Only one in a hundred would actually set-up to name and shame.
