A school board member in Greeley, Colo., has started bringing his gun to school board meetings after, he says, he received threats over his regular radio broadcasts attacking the Rev. Martin Luther King Jr.

He describes it as a letter he received from a listener three years ago. It can also be found on a web site, martinlutherking.org, which is run by the white supremacist group Stormfront....

For what it's worth, the Tribune spoke to Clayborne Carson, the founding director of the Martin Luther King, Jr., Research and Education Institute... who said that many of the factual claims in the commentary -- that King had extramarital sexual relationships and plagiarized an academic paper -- are substantiated.

As a historian, all that is irrelevant," Carson said. "King is considered a great person not because he was born a great person but because he was part of a great movement that achieved a major change. To say he was not perfect or had flaws doesn't matter."
