I think the reason people are concerned when they hear that doctors, research scientists, other professionals, or anyone associated with the analytical, scientific, medical, educational fields is also associated with terrorism is that, religiously motivated or not, terrorism is the recourse of the desperate and chews up the lives of the underprivileged.
So I was shocked when I heard that at least one of the London bombers was a qualified teacher, that qualified doctors were involved in the abortive attack on Glasgow airport. As I understand it, the typical terrorist cannon fodder are not typically the kind of people who would have the financial, social, or educational background to be professionals.
I really hope this is just a case of an excess of zeal on the part of French law enforcement, as the alternative - that a particle physicist, a man of knowledge, logic and words - could be actively involved in terrorism is far scarier than 100,000 dirt-poor farmers armed with rocket-launchers. It would mean that even those who should know better are turning to the dark side.
Fuck that for a laugh, mate.
