In the wake of Walter Wallace Jr.'s death at the hands of Philadelphia police, his family is speaking out about the horrific incident, including his two young sons, one of whom blamed his father's untimely death on racism. His oldest son spoke about how much his father meant to him and how "white racist cops" were the ones responsible for taking his dad. He tearfully raised his fist and declared "Black Lives Matter," following his remarks. 

Wallace's mother also spoke during the press conference, where she called for an end to the rioting and looting. She also explained how the officers on the scene completely ignored her pleas to de-escalate the situation despite her son going through a mental health crisis at the time.
