Black cop on scene at Gates arrest ...

... says in a letter that it was Gates who set back race relations: "[Gates] 'may have caused grave and potentially irreparable harm to the struggle for racial harmony.'”

Sgt. Leon Lashley has said that he's also been called an "Uncle Tom" for supporting [white] officer James Crowley.

I think Lashley's going a bit overboard with the "potentially irreparable" bit, but this just goes to show you (along with the hassles the 911 caller had to endure) the problems one may encounter by going against the prevailing cultural/racial orthodoxy.
