The Washington Post's A City in Turmoil presents a more expansive view of the riots which started on 14th St NW and later impacted H St NE. WaPo sets the stage for the map:
On April 4, 1968, civil rights icon Martin Luther King Jr. was assassinated in Memphis. His murder sparked unrest that same evening in Washington D.C. Over the next few days, violence, looting and arson enveloped the city. Here is an account of the events that damaged -- and destroyed -- large swaths of the District.
The 1968 Riots in Washington, DC, on the National Archives blog, describes some of the damage resulting from the riots. One account retold in the blog post:
Mr. Jesse McCain an African American man over the age of 50 whose barbershop at 643 P St NW, just off the 7th Street riot corridor, was made a total loss on April 5th, wrote: "I AM TOO OLD TO BE WORRYED ANY MORE I JUST DON’T WANT ANY MORE BUSINESS."
The pictures below make clear why Mr. McCain felt the way he did.
