Should be is the key word but nowhere does it say it is illegal.
In addition this is still interesting news because if he IS doing this then there is some admission of guilt involved. Much like M.J. paying off that kid to hush him up.
This will be interesting nonetheless
Sorry, but there's no admission of guilt here; as I see it, this is a case of an individual attempting to save himself a huge (Hugh??) pile of cash. Were I in a similar position (under attack for something that I wasn't guiltly of, but with enough circumstantial evidence for an overzealous prosecutor to take to a grand jury), I would look for the cheapest and easiest way out.
In other words, since Rush is purportedly off the meds and under rehabilitative therapy, his best and cheapest course of action is to make a deal - I'll stay off the meds and you leave me alone. Since the procesecutor doesn't want to agree to this, then off to trial we go - at $600 and hour for Roy Black. I'd think that saving the money is better than a phyrric victory that costs millions to prove innocence.
