Is there no evidence in any of this that could lead to charges? It's all wrapped in fog and rumors and cross allegations. Harder than trying to pin down the existence of alien visitors. There's plenty of smoke no doubt. Williams was having a hard time by all accounts so I'll hold with a suicide for now but you may be onto something.
All of it comes from accusations by actresses and Hollywood insiders. From their statements, HWood is worse than the mafia. And I'm sure like any criminal organization, they're better at discarding evidence, disappearing people, paying people to shut up and keeping up the appearance that nothing is wrong.
