In Philadelphia, city officials have released body camera footage of the police killing of Walter Wallace Jr., the 27-year-old Black man who was shot by two police officers while having a mental health crisis last week. The video shows police officers Sean Matarazzo and Thomas Munz shooting and killing Wallace as he stands outside his parents’ home carrying a knife. A woman in the video can be heard repeatedly saying Wallace is “mental” as the officers point their guns at him. At one point, Wallace’s mother stands between the officers and Wallace. In one video, a male voice can be heard saying “Shoot him” and “Get him.” The officers then fire at least seven rounds each at Wallace, who falls to the ground. Wallace’s mother rushes to him, saying, “You killed my son.” One of the officers says, “He was f—ing chasing us.” Wallace never gets closer than 10 to 15 feet away from the officers.
