Apparently they successfully attacked a 3rd floor toilet. On the face of it, one could think it almost farcical. However, my interpretation is that non-Muslim terrorists (aligned with the anti-globalization communist movements of Europe) are (re-)adopting the modus operandi of out islamic friends. When anarchists and commies start to adopt the tactics of jihadis, there is reason for concern. There are pro-jihadi radical leftists in every Western country, as we all know. (Sorry if I have lumped all radical leftist commies with the same brush.)
I think the "unification" of these groups - Muslim and leftist extremists - is one of the biggest things to worry about. It is known that there have been contacts between ETA and the jihadis in Spain (and that ETA was probably involved, at least from a supply and training point of view, in the March 11 bombing) and these groups have a long track record of supporting each other. But I think they haven't quite united their forces yet, although ideologically they seem to find no conflict between authoritarian Islam and authoritarian Marxism, so it's probably only a matter of time.
Bump!
Canadianally, you are more then likely correct. This group is nothing more then lefty-nuts who protest everything under the sun and stir up trouble that has anything to do with everything ~ from soccer game matches between two local teams to "political causes" to highschool students "striking" against the "establishment", if there is a "uproar" in the country you can bet your dollar these wack-jobs are right smack in the middle of it always wearing bandanas to cover their faces as most cowards usually do. You should of seen it a few months ago when Greek students locked themselves into their schools, pretty comical to see parents storming the schools to get their kids who were "striking". LoL!!!
