If police can literally get away with murder, I hope you have no expectation that merely conspiring to deprive citizens of their constitutional rights will be prosecuted.
If guys like Alan Gottlieb and the Second Amendment Foundation were smart, they'd find some black dude (to neutralize the 'racist' thing) who gave up his gun to the police but otherwise has a clean record, and use him to SUE, SUE, SUE. Sue, baby, sue.
