Hmm. People phrase their public "apologies" carefully for obvious reasons, I think, the main one being the same reason you don't admit culpability when there has been a traffic accident. You wait for all the facts to be collected.
That doesn't mean you aren't accepting responsibility and feeling sorry internally (and even making amends). I don't think we should judge on public and "media-blessed" apologies.
As for apologies in case anyone has taken offence (when, at the same time, most people haven't), well, I think those are daft anyway. People take offence for all sorts of stupid and rationally unjustifiable 'reasons'.
