Democratic presidential nominee Joe Biden and his running mate Sen. Kamala Harris (D-Calif.) have condemned the violence and looting that erupted in Philadelphia following the fatal police shooting of an armed African American man.
The city experienced a second night of unrest on Oct. 27 after the shooting of Walter Wallace Jr., who was armed with a knife and described by relatives as suffering from a mental breakdown, during an Oct. 26 confrontation with police officers.
