Pennsylvania governor Tom Wolf ordered National Guardsmen to Philadelphia on Tuesday, following a night of riots that left 30 police officers injured and various businesses vandalized.
The riots began after police shot and killed 27-year-old Walter Wallace Jr., an African American man, who officers said approached them with a knife. Video of the incident showed Wallace walking towards officers with his mother attempting to hold him back, and when the camera points away police fire several shots.
“The Pennsylvania National Guard is mobilizing several hundred members…[to] assist local agencies in protecting life, property and the right to peacefully assemble and protest,” National Guard spokesman Lt. Col. Keith Hickox said in a statement. “We are able to conduct operations in support of civil authorities to enhance local law enforcement's ability to provide continued public safety and critical infrastructure security.”
