Given that Bin Laden received a huge 'contribution,' just prior to EA-990; the point is strong.
The bad news is that the connection has been known since the beginning - again ignored.
Also, the FBI was methodically locked out of an obvious criminal attack - ala TWA-800 - where's the accident report?
It's pretty naive to NOT make the "...don't go there" connection.
I'd suggest looking at political contributions in the wake of EA-990. That was always Clinton's MO.
