Take it easy.’ The guy says, ‘I don’t give a [bleep] who you are’ and hits him in the face. Another man hits him from behind. The officer goes to the ground. They’re beating him and he’s about to lose consciousness. He pulls his weapon to defend himself at that point, fires one shot, and kills one of the individuals who happens to be the father of the 4-year-old.”
