Somewhat alarmist piece. The Lib-Dem spokesperson quoted halfway down Is a voice of reason…”Domestic extremism” is not [yet!] a recognised offence in UK law. Il Silvestre, who allegedly planned to attack IBM in Switzerland because they oppose nano-technology, are worth studying, but to turn them into a coordinated European movement is something of an exaggeration. On the other hand, scholars of terrorism have been waiting for something new to come over the horizon for a while. This may or may not be it…watch out for the instant experts!
