The police team which mistakenly shot the Brazilian Jean Charles de Menezes came under scrutiny again when it emerged that the unit had been involved in the killing of another man. But the death of Robert Haines did not attract the kind of attention the Menezes case got because it happened as police tried to stop an alleged armed robbery. The shooting is being investigated by the Independent Police Complaints Commission. Now Mr Haines' widow has spoken out about her husband's death.
