The media owes the Duke players an apology, too.
They were tarred, feathered, and run out of town on a rail, and this after it had become obvious that the "evidence" was anything but.
As for Imus, I don't really care about him, but the precedent is something to keep an eye on.
I'm not holding my breath waiting for the Sharpton/Jackson Dynamic Duo to go after the huge and profitable rap music culture whence that language came. Sure as hell Imus didn't learn "ho" from hanging around the Lion's Club. "Ho" is not a word that came out of racist white culture.
