Jean Charles Demenezes was a brazilian who was shot dead by London police after the bomb-blasts, because he was looking like a Muslim and he came out of a building they were spying on. They even declared to the press that he was a pakistani. They made such ridiculous excuses to cover up such as, he was running away and was wearing a thick jacket and so on. That is the kind of tragedies that happen with racial profiling. Airport security check should be done equally on all travelers.
