The suspect hasn't been charged with insider trading. (OP said those "in DC seem to be able to do everything listed.")
I think that was the point GP was making.
There is circumstantial evidence. We need to collate that. But nothing trumps direct evidence. If someone has that I will bend over backwards to find a way to securely connect them with, at the very least, a reporter who can document it so it shows up in an internet search when an empowered staffer starts down this path.
