Umm, no, you didn't make any mistake... they were waiting on him to apologize; because this isn't an apology:

“If I offended anybody in Pahokee or (anyone who) has to do with Pahokee or in the schools, I apologize; and I want to make sure it’s understood that is not what was meant by it (the comments) at all,” Kiffin told the newspaper. “It was just an energetic breakfast with some of our donors. Didn’t even know that there was a camera present when the things were said.".

“It just wasn’t something that was meant to go in front of the media and make a big statement. ... It’s why immediately that day I apologized and made sure that everybody understood it wasn’t my intention to offend anyone at the University of Florida or coach Meyer.” - Kiffin

Basically, what that says is, "If some people are overly sensitive, I'm sorry something is wrong with them.". It also infers that he meant what he said; but was just sorry that he got caught by the media.

That's the equivalent of somebody "apologizing" in court, and saying they're sorry about what happened to their victims, instead of being accountable and saying they're sorry for WHAT THEY DID. What they really mean is, they're sorry they got caught by the police.

Oh yeah, and if you don't think you did anything wrong in the first place, what are you "apologizing" for?
