"Mistaken" renditions

Just what is a "mistaken" rendition?

From AP comes this amusing claim (amusing as long as you're not one of the victims):

The CIA's independent watchdog is investigating fewer than 10 cases where terror suspects may have been mistakenly swept away to foreign countries by the spy agency.

"Mistakenly" swept away? What, they thought they were putting them on a domestic flight and they went to the wrong gate at the airport? Got confused between Lebanon and Lebanon, Indiana? No, that wasn't quite it:

For instance, someone may be grabbed wrongly or, after further investigation, may not be as directly linked to terrorism as initially believed.

So, if you were grabbed "rightly" (in other words, George Bush or John Ashcroft or Alberto Gonzalez said you were a terrorist and you were the right Jose Padilla, not the wrong one), or if you were directly "linked" to terrorism (e.g., you once Googled "Osama bin Laden"), then rendition to foreign countries where you "might" be tortured is perfectly ok, and not even worth discussing, nevertheless investigating.
