That's been my number one question for a while now also in regards to other cases and other 'apologies'.

Would it makes sense for the perpetrator to go to the police and admit guilt? Would there still be consequences in that case? And if so, is that part of the reason why these apologies always seem to be very vague about details?

And if all that, should we expect anything less from an 'apology'?

Exactly, what's an apology without punishment? There have to be repurcussions of illegal behavior. Else I would just say sorry after murdering someone and get sympathy.

Remember, he's not sorry he did it, he's sorry he got caught.
