I wonder if the thread starter has lost someone or something? People say things in grief and anger they don't always mean. Or they could just be an extreme right winger... Possibly a BNP type?
The important thing is to keep a level head.
Was just reading something on BBC to the effect that the suicide bombers are generally glassy eyed dupes, true programmed killers in the classic "hashishim" (asassin) mode- they've basically been brainwashed by a wierd cult into doing this. The article said how the people to go after are the controllers, the people who activate and run the bombers, because they do not want to die and therfore can be caught while doing dry runs, recces, and so forth.
In fact a large part of the controller's job is to keep the would-be assasin / terrorist gee'd up in a state of sufficient religious fervour that they don't back out. Cynical, no?
I'm not being "soft", btw- IMHO people like that, evil, dirty old men who take all of a young person's energy and drive and use it to turn the kids into walking bombs, deserve to be executed in as painful and unpleasant a manner as possible. But you have to catch them first...
Do you see what I mean, thread starter? The point of successful criminological measures is to find the people who actually did the crime, and punish them, not yet more hapless bystanders.
