The banks placed the trades for customers -- so its the customers and not the banks that knew about the 9/11 attacks in advance!
Nothing in this piece of crap suggests otherwise.
Verbal abuse and attempts to discredit are just ploys people are less and less inclined to fall for these days. It certainly doesn't proove anything except that maybe you are afraid of the truth.
Juan Diego is correct about one thing here. The relevant question is "who were the customers who bought all those puts?".
The brokerages and banks are relevant only in that the answer should be found in the records they keep of orders placed and executed.
If significant blocks of orders trace back to particular customers, that would be a strong indication that something was up.
The World Socialist Website has an excellent article on October 5, 2001 entitled "Suspicious trading points to advance knowledge by big investors of September 11 terror attacks." See:
