Well I know one of them was definitely on their watch list, not that it helped them stop him. The brother of this one that's supposedly still on the run is making all sorts of claims, like the guy was supposed to blow himself up but had a last-second change of heart, and he'd (the brother) like him to surrender himself as he says he would rather his brother was in jail than in a cemetery.
I must say, I feel the reverse. What are French jails like anyway? They stormed the Bastille, you know, and they were just peasants!
Seriously though, I doubt they're like the American supermax or whatever yaz have over there.
