More information has come to light about Walter Wallace Jr, the man who approached Philadelphia police while brandishing a knife, and whose seemingly justified death at their hands has ostensibly sparked the latest round of rioting. As the local ABC affiliate in the city reports, Wallace was an “aspiring rapper” whose “central themes” in his music were guns and shooting people. We are also told that he rapped about social justice, though it is not clear how someone can be fascinated with shooting people while simultaneously concerned with social justice. Wallace has a lengthy rap sheet. He had a prior arrest for assaulting a police officer, though it’s not known whether the officers responding to the 911 call shortly before his death knew about that incident.
