I see --- so we are actually pretty much in total agreement about compensation, then.

I would not use the word "arrested" because these men were taken into a system that was explicitly extra-legal and were not accorded due process. Also, given the warrants issued in both Italy and Germany, it appears that the local and national authorities were not made aware (odd that this does not appear to have occurred in Canada, where the local authorities were complicit and have recently paid millions in compensation to Arar). "Detained" sounds, frankly, a bit too neutral given the ultimate fate of these and many other men. We did not take them to Syria for interrogation of the usual sort, for instance.
