Intelligence experts around the world are said to be in little doubt that bin Laden was responsible for the outrages.
They admit that by the standards of a courtroom the evidence is only circumstantial - but say that taken together it is overwhelming.
It does not appear yet that any of the more than 100 people detained in connection with the bombings have directly implicated bin Laden.
However a suspect held at New York's JFK airport trying to travel on a bogus pilot's licence is reported to have provided "useful information" pointing towards him.
Intelligence experts are reportedly most swayed by telephone intercepts by security services in which alleged al-Qaida members celebrate the attack in a way apparently indicating prior knowledge.
In one, a suspect is heard to say - "We've hit the targets."
I think the leap to your conclusion, "I don't believe any was provided", is a greater leap than my opinion that convincing evidence was provided.
