That'll fuck 'em.

Seems the Senate has done it.....

Senate passes bill allowing 9/11 victims to sue Saudi Arabia

I think it'll be hard to prove that the House of Saud was complicit. And you will need to do that if you are going to go to trial.

Not that I believe they weren't complicit,mind you.....  even if they didn't know the plan was to kill thousands. But I believe that someone knew that there was going to be an attack, even if not when.

But it WILL be hard to prove. You might find underlings that were, but that too will be hard to prove. The only real witnesses were flying the planes that day. And they ain't talking anymore.....
