In both of the former cases, evidence was held back by the US government:
This time, again, evidence is scarce, and maybe US agencies with their wealth of information could help. The question is: why has the US government refused to help Germany in their war on terror and in bringing those responsible for 9/11 to justice? Why would they not cooperate fully?Last month, a German court rejected a bid by Mzoudi's lawyers for the German government to allow statements from bin al-Shaibah, accused of liaising between the Hamburg cell and al Qaeda leader Osama bin Laden, to be used in his trial.
Bin al-Shaibah was arrested in Pakistan in September 2002 and transferred into U.S. custody. Mzoudi's lawyers have said his evidence was crucial to their client's case.
The material was passed onto the German authorities by U.S. authorities to help German investigations against alleged Islamic extremists, but with the explicit understanding it would not be used in any court proceedings.
(They could at least help proving that he was in Afghanistan: "A lawyer for Garnaoui dismissed the charges, saying there was no proof his client was in Afghanistan and that other evidence was based largely on police informants.")
