Usually these statement read like a lawyer wrote them (because a lawyer usually did), and usually you can't be sure if they're apologizing because they feel terrible about what they did, of if they're sorry they got called out on what they said. More often than not, it's the latter.
An actually good apology doesn't just say, "Whoops, sorry about that," it explains why the person is sorry, why they know what they did is wrong, and what they plan to do in the future so that they'll do their best not to repeat the problem. As I always say, when you hear a good apology, you know it.

Hill was a guest on The Tonight Show last night. This is how one apologizes.
