youngmafbog - but he is not innocent, that is the point that you don't seem to be getting.
The parties involved all understand that LR is guilyt of inappropriate behaviour - but that does not mean that it can be proven in a court.
The term 'insufficient evidence' is a polite way of saying - 'We know he did it, but we don't have a strong enough case to go to court.'
That does not make LR 'not guilty', nor does it make him 'innocent' - it means what it says, there is insufficient innocence.
So the decent mature thing to do is to emerge with a degree of dignity for all concerned - including and especially LR - by making a reserved apology (as opposed to an unreserved apology) which means he comes away from a damaging situation with minimal damage.
His pig-headed 'I've done nothing wrong ...' stance does make him look - as advised - unfeeling and arrogant, the very attitudes that have brought him here in the first place.
