This a great way to come out second in the battle against terrorist financing. Not to toot our own horn, but typically terrorist organisations and terrorist financiers are profiled in World-Check years before OFAC. By the time OFAC recognises a terrorist-affiliated charitable organisations or nonprofit, it may have had years of operation inside the US, raising funds, and sending them onward to their home base, to purchase weapons and other supplies which aid in their violent operations.

How can one of Treasury's most important agencies not use a comprehensive terrorist watch list? Perhaps I am missing something here, but whoever is in charge of fighting terrorism financing should be fired and sent
packing. Those tax returns represent a potential source of valuable information on possible sources of terrorist funding. They need to examined by investigators utilising the best commercial watch lists available. To do any less is at best negligence, and probably constitutes governmental malfeasance of the highest order.
