From nps.gov:
After meeting with members of Martin Luther King, Jr.’s family regarding the recently-dedicated Martin Luther King, Jr Memorial on the National Mall, Secretary of the Interior Ken Salazar and National Park Service Director Jon Jarvis announced a plan on February 10, 2012 to correct the “Drum Major ” quote to more accurately reflect the meaning and intent of Dr. King’s original statement.
The plan calls to remove the paraphrased quote and replace it with the original quote in its entirety. The monument would no longer read “I was a drum major for justice, peace and righteousness.” The quote would read, “Yes, if you want to say that I was a drum major, say that I was a drum major for justice. Say that I was a drum major for peace. I was a drum major for righteousness. And all of the other shallow things will not matter.”
The NPS expects that portions of the granite stones carrying the current quote will have to be replaced. They are exploring options to secure funding for the correction, but have set a deadline for the fix. The work should be completed in time for the celebration of Dr. King’s birthday in January 2013.
