Blame the victim
This is an apology:
I did have a relationship with Miss Lewinsky that was not appropriate. In fact, it was wrong. I misled people, including even my wife. I deeply regret that. -Bill Clinton, 1998
This is not:
I have always been very passionate about politics and sports and this time it got the best or worst of me. Thought of the leaders of both parties jukin’ [sic] and high fiven’ [sic] on a golf course, while so many families are struggling to get by, simply made me boil over and make a dumb statement, and I am very sorry if it offended anyone. -Hank Williams Jr. on comparing President Obama to Hitler.
