In Philadelphia, federal agents arrested prominent civil rights activist Anthony Smith at his home Wednesday over unspecified charges related to protests against police brutality that erupted in May. Smith’s lawyers are questioning the timing of the arrest, which came as protests continued against the police killing of Walter Wallace Jr., a 27-year-old Black man who was shot and killed by two Philadelphia officers during a mental health crisis. Philadelphia’s mayor ordered a curfew overnight, following incidents of arson and looting on the sidelines of mostly peaceful protests on Monday and Tuesday. Meanwhile, the Philadelphia Police Department says it has launched an investigation into officers who were filmed smashing the windows of an SUV during protests early Tuesday morning — then beating the driver and removing a small child from the back seat.
