Matt Steinglass asks:

[H]ere’s my main question: what exactly is so hard about getting terrorists convicted in American courts? Under US law, even “providing material aid” to any “terrorist organization” is a felony...[A]re you seriously telling me that the Bush Administration’s torture regime has so thoroughly bolloxed the entirety of the evidence regarding detainees at Gitmo that we can no longer even prove they were doing anything to support any group on the State Department’s list of terrorist organizations? Any such group whose actions have resulted in “the death of any person”? If we can’t prove that about these guys, what are they doing in prison?
