It happened before with London and Madrid bombings. But right now with European people being so fed up with the latest news it could be taken on the streets. I'm afraid that if you're a respectful Muslim and a peacful one no one will take that into condiseration when you meet up with them on the streets outside of those 'Muslim areas' in Eastern Europe. This could bring out the worst of the people throught the Europe...Wow, this is going to be Europe's 9/11!
