What did Charlie Sheen mean?

For those of us non-Americans living outside the U.S., 9/11 always had too many questions even at 10am on 10/11.
But Charlie Sheen is walking on egg-shells in my opinion.
Living 15,000km away, I wouldn't be game to say 1/2 the things that he's intimating.
I remember an employee of ours said to me the next morning - "don't believe it sir, it's all about oil".

Was he right?
Will we ever know?
Is there a conspiracy?
Will Charlie get his way?

I love that guy. He's a great actor and he's got two of them to even get this far.
I just hope and pray that he doesn't have an "accident" before he goes any further.
It's been 2 months since the "letter" and I can't see any follow up anywhere.
Is it a dead duck already?
Not Charlie. I mean the letter.
