According to the news, why was the Brazilian man killed? [originaltext] Bra

Brazilian officials arrive in London today to meet a team investigating the shooting of a Brazilian man police mistakenly thought was a suicide bomber. The Brazilian government wants to get a clear picture of the events leading up to the shooting of Jean Charles de Menezes, and to find out if media reports about the investigation based on a leak are accurate. The mother of Mr. de Menezes, Maria, says the policeman who killed him should be punished. Tom Gibb reports from Brazil:
     Maria de Menezes said her only desire now was to see justice done. She said she didn’t want to see any other mother suffer as she has. The family say they are glad that documents and pictures of Jean Charles de Menezes after he’d been shot which contradict the original police version have been made public. They say they knew from the start that he had no reason to run from the police and world never have jumped over a barrier of an underground station.
