IF they lied?
The video tells the truth. The cops don't.
The Rocky says:
Police officers who intentionally undermine investigations by tampering with evidence or making false statements erode the integrity of the justice system and the public's confidence in it.
And that is why good cops should not countenance the actions of the bad cops. And when they do, they are complicit in the public's lack of faith and distrust in the system.
Cops can't have it both ways. Either they work for justice, or they protect the uniformed thugs in their midst.
Bring a video camera downtown during the DNC. Record history.
