Well, NPR kept stating yesterday that Abu Faraj al-Libbi was not on the FBI most wanted terrorist list, and that there was no reward for him. Yet news outlets have claimed up to USD5MM reward from the US (the actual amount for Anas Al-Liby) and USD300,000 from Pakistan for his capture. So it does seem very plausible this is the wrong fish.
There's also conflicting statements in the media about Al Libis background.
According to this post, Former CIA counterterrorism chief Vince Cannistraro said [Faraj] al-Libbi, unlike Shaikh Mohammed, never traveled to the West and "wouldn't know San Diego from Queens while the FBI site and most of the rest of the media correctly states that Anas Al-Libi had been living in the United Kingdom, which, IMO, counts as part of "the west."
Apparently, CNN has also repeated the interview with Hamid Mir where he's claiming that Anas Al Libi and Abu Faraj Al Libbi are two seperate people that have been mixed up.
These folks use so may different spellings for their names as well as aliases, is hard to figure out what's going on at times.
