AP PHOTOS: Washington then and now following King’s death

Riots erupted in America’s capital in the hours after Martin Luther King Jr. was assassinated on April 4, 1968. Grieving and angry, rioters smashed windows, looted and burned buildings for several days.

With the Washington, D.C. police force overwhelmed by the rioting, the federal government deployed the National Guard to protect government buildings and maintain some semblance of order in the city.
