WASHINGTON (CNN) -- Acknowledging the odds are against them, relatives of the September 11 attacks filed a 15-count, $116 trillion lawsuit Thursday against the company run by Osama bin Laden's family, Saudi Arabian princes and Sudan.
Calling themselves Families United to Bankrupt Terrorism, the plaintiffs are suing seven international banks; eight Islamic foundations, charities and their subsidiaries; individual terrorist financiers; the Saudi bin Laden Group; three Saudi princes; and the government of Sudan for allegedly bankrolling the terrorist al Qaeda network, Osama bin Laden and the Taliban
CNN - $116 trillion lawsuit filed by 9/11 families

I have some questions that I hope someone can clear up for me:
a) If you could prove that these organisations were funding al Qaeda et al, shouldn't this be in a criminal court rather than a civil one?
b) Does a court in America have any power to remove this sort of money from overseas entities?
c) Do international courts have the power to remove this sort of money?

I get the feeling that these questions are pointless, as this lawsuit has bugger-all chance of succeeding, but I thought I would ask anyway.

Thanks in advance
