Nope, nothing to do with the jihadist here. Its a domestic issue and those who are doing the bulk of the rioting are ethnic Greeks. Such demonstrations have been held on a regular bases across the country for almost two years now in opposition to the government's plan to amend Greece's constitution. Last year more then half the school year in Greece was lost because of riots, demonstrations and students taken over schools and unviresities. Greek anarchists, students, unionists and party activists because of public anger over government economic policy and reforms in the academic fields. On Thursday and Friday(12/4/08 & 12/5/08) the Nurses Unions in Greece went on strike, those strikes led to Saturday night's riots, those riots had the police out in force to stop them and it was during those riots that the kid was accidently killed by a police officer. This killing set off more riots 'in the name of the kid who was killed' said some, but in reality its over their discontent with the government trying to make economic and academic changes in the country, as well as hooligans taken advantage of the situation to riot for basically nothing. This is why you are seeing so many students, they are against the reforms that the Greek government wants to make in the universities. Unfortunately this kind of rioting is common thru out Europe thanks to their socialistic culture that is a breeding ground for anti-capitalist leftists, anarchists and hooligans, mostly youths and students are involved behind the riots and more of then not they come from wealthy familes. The kid who was killed went to one of the most expensive and private schools in Greece.
