So, if you're innocent you're stuck trying to prove the negative in the court of public opinion. Get that shit on the record, open up discovery and the accuser can put up or shut up.
If he's clean, he's got a defamation suit (notoriously hard for your average Joe to win due to the damage component, but if Heath can show that he's losing professional opportunities in the wake of the accusation he's got a colorable claim).
My guess, and I like Heath, is that there is some nugget of truth here. Seeming nice, normal guys are pretty quick to send their cockshots around the textiverse. Or the "locker room" nature of the set was over the line. And, if so, then fuck it...he should have known better.
You and I have both been around women who threw themselves around and made jokes about it. Or I assume you have. If so, you should also know the danger of rejecting that and pissing them off. A friend of mine very nearly lost his company because he didn't give this girl a promotion and she claimed he came on to her in his office.
It wouldn't surprise me if this ugly ass woman, looking old enough to be his great grandmother, was flirty and sassy and made some off-color comments like "you're looking good today, sugar, don't make me spread this all over you..." and he did some off hand flippant "you couldn't handle this" type of rebut. It's not in the male nature to get filled up with righteous anger when some old floozy flirts with you. In fact, the true nature of chivalry almost requires that you respond in kind and then get the hell away from it.
Even so, wes, how in the hell can he PROVE in a court of law that he never said anything to her if he didn't? She has her traumatic, tear-choked "memories" and there's nothing he could say or do which would effectively counter that. It's a no win situation. And it's symbolic of what I consider wrong with today's society. You can talk about guilt/innocence/litigation all you want but that's a naive stance. You've already convicted Heath in your own mind with your "he probably" and "it was likely" position. It doesn't have to be true. You're going to be punished.
Part of her lawsuit is that she was hanging out in the men's restroom working on clothes and Warren Sapp came in and took a piss. She was in the men's freaking restroom. That's where men go to take pisses. But he's got to be fired because she was offended.
The ONLY reason this hideous hag made the allegations is because 1) she got old and was replaced by somebody younger and brighter and 2) she got fired for stealing from the network. And now he's settling with the network -- part of which is them paying him off so he doesn't sue them.
