PHILADELPHIA (CBS) — Local officials today observed the anniversary of Dr. Martin Luther King’s assassination.

The Philadelphia Housing Authority dedicated a plaque at 13th and Fitzwater Streets, where Dr. King held a streetcorner rally in 1965, during a tour of northern cities to promote his civil rights campaign.

And Mayor Nutter (in photo) declared the 12th annual “Human Family Day,” to honor Dr. King’s vision of a colorblind society.

“It was something beyond desegregation,” the mayor said today at City Hall.  “It was a community where fellowship would cross any lines of division.”

US Rep. Chaka Fattah (D-Phila.) attended both events, noting they are what gives meaning to Dr. King’s death.

“The idea that we have a connection, that there is more about us that is similar than is different, is so important at this time,” he said.

Dr. King was shot to death in Memphis on April 4th, 1968.
