Exactly- they practice selective policing- their bosses get orders from the left in power, and conservatives become victims of their selective policing as a result.
I remember watching a video,of the left being violent in front of a church. The cops stood there allowing it UNTIL one of the church members fought back, then the member was prevented fro. Defending themselves by the cops. The cops even let the rioters go into the church and do damage and disrupt,the service.
So many incidents where the left attack the right, cops stand by and do nothing until the right start to fight back, or try to protect themsleves, then it is the right who get arrested.
