The Black Lives Matter message is all about "building trust with the police"  --  at least with such of the police as are left after getting shot at by the people inspired by Black Lives Matter.

Mother of Police Shooting Suspect Blames Black Lives Matter

The mother of one of two central Pennsylvania teenagers charged with shooting at police officers last week contends the Black Lives Matter movement is to blame for his actions.

"They are in jail for doing what Black Lives Matter wanted them to do: shoot at cops," Luz Rentas wrote in a statement given to a number of news organizations over the weekend. "The truth is that these are two punk kids following the orders of an irresponsible organization and now they're gonna pay for it."

The co-organizer of a Black Lives Matter chapter in Lancaster said the group rejects using violence to solve societal problems.
