The president of a Pennsylvania police union responded to Black Lives Matter activists demanding accountability for the police killing of a black man by calling the group a “pack of rabid animals.”

Philadelphia Fraternal Order of Police President John McNesby made the statement Thursday during a rally held by and in support of police, according to NBC Philadelphia. The “Back the Blue” rally was in response to a protest the week before by members of Black Lives Matter held outside the house of Officer Ryan Pownall, who fatally shot a David Jones in June.

Pownall, a 12-year veteran, shot Jones in the back as he fled from a traffic stop. Police said Jones was armed with a gun. This marks the second time Pownall has shot a black man in the back as he was fleeing. In 2010, he shot Carnell Williams-Carney who ran from cops while having an illegal gun on him.

“That was the day I took my last steps on my own,” Williams-Carney, the now 36-year-old shot by Pownall, told Philly.com from his wheelchair. “I’ve been in a chair ever since.”
