Following the September 2001 attacks in New York, and again after the bombings in Madrid in 2004 and London in 2005, law-enforcement authorities across Europe launched mass-arrest operations, undertook widespread surveillance of mosques, carried out stops and searches of people who appeared to be Muslim, and used other intrusive measures that disrupted the lives of – and in many cases humiliated – law-abiding European citizens.
继2001年纽约911袭击事件、2004年马德里爆炸案和2005年伦敦爆炸案后，欧洲的执法当局就发动了大规模的逮捕行动，对清真寺进行监视、对于那些看上去像穆斯林教徒的人进行询问和搜查；并采取其它一些侵犯性的措施，甚至一些让人难堪的方式、扰乱了欧洲遵纪守法的普通公民的生活。
