The family of an innocent Brazilian man shot dead by British police who mistook him for a would-be suicide bomber, on Friday called for London Police chief Ian Blair to resign.Jean Charles de Menezes was shot eight times at point blank range as he boarded an underground train on July 22, a day after a failed bomb attack on the city’s transport system.Blair said at the time that de Menezes was under surveillance as part of a manhunt to catch the four bombers, and had refused to respond to police challenges. The next day, the force admitted they had shot the wrong man and apologised.‘‘For the sake of my family, for the sake of the people of London, in Jean’s name I say that those responsible should resign, Ian Blair should resign,’’ de Menezes’ cousin Alessandro Periera told a news conference.In an interview to BBC Radio, due to be broadcast on Saturday, Blair said he had no intention of resigning. ‘‘No, not at all. Obviously one has to reflect other people’s views, but the level of support I and the Met have received over the last few weeks I think outweighs these particular events. ‘‘I think that’s the important point, really, that tragic as the death of Menezes is—and we have apologised for it and we take responsibility for it—it is one death out of 57,’’ he said. Blair insisted his men had acted in good faith and said there had been no attempt to cover up events. The Brazilian government announced it would conduct its own inquiry into the shooting and that a Brazilian team would visit Britain soon.Meanwhile, the British government is facing demands to close down a London-based radio station broadcasting calls for attacks on British troops in Iraq. Al-Tajdeed radio, run by a prominent Saudi dissident, carries songs calling on Muslims to join the holy war against coalition forces. On May 21, the station broadcast a speech by Abu Musab al-Zarqawi, the leader of Al Qaeda in Iraq.
