the threat of fear and defeatism
"The armed plainclothes squad pursued a man essentially because he was not white and was wearing an unseasonably thick coat. They allowed him to board and leave a double-decker bus unchallenged. Then, when he ran away from them and jumped on a tube train, they apparently decided that he must be a bomber and shot him eight times, seven times in the head and once in the shoulder.
These crack anti-terrorist marksmen acted with about as much cool professionalism as the American gunman who shot dead a turban-wearing Sikh immediately after 9/11, for supposedly looking like a Muslim. But they were only acting on the message that has come from the top of the UK political and police establishment since 7 July. The panicky message has been that these few bombers allegedly pose an 'unprecedented' threat to our way of life, so that any liberty can be sacrificed or draconian measure justified if it is supposed to help stop them."
