“Execution” is the only word for it. He’s shot in the chest at point-blank range, his arms being pinned by the other cop.
I believe that you can hear his last words: “Please don’t!”
Be warned; this video may leave you shaking and ill. It did me. It also shows you just why the Baton Rouge police force has reacted to protestors so violently since this killing became public. It is apparently the black public is “handled” there.
