The answer to that has to be yes. Apart from the big things such as terrorism, on an every day level as well.
There was an incident in my town a few months ago, where worshippers (or should I say men) visiting the local mosque parked their cars on double yellow lines (restricted areas)and the local traffic wardens (don't know what you call them) issued them with tickets. The upshot of this was that a mob came out of the mosque and attacked the wardens, bringing the police on the scene.
For the life of me I just couldn't imagine the same thing happening outside a chrisian church or synagogue.
