Sir Ian Blair, the Metropolitan Police Commissioner, is telling a newspaper he wants to make sure his anti-terror investigators aren't being affected by criticism they blew an innocent man's head off.

An excerpt from the AP story carried on CTV.ca:

"We have to concentrate on how we find the people who are helping or thinking about planning further atrocities," Metropolitan Police Commissioner Sir Ian Blair was quoted as telling Sunday's News of the World tabloid newspaper in an interview.

Blair told the newspaper he is making "sure anti-terror investigators are not affected" by the criticism.

"I have told them 'This is not your problem'" Blair reportedly said. "For myself, it's a job I have to do. And I am not going to be distracted from the main job which is finding the terrorists."

Blair told the newspaper he did not know the Brazilian was not connected to the attempted bombings until 24 hours after he was shot.

"Somebody came in at 10:30 (Saturday) and said the equivalent of 'Houston we have a problem,'" Blair was quoted as saying.

"He didn't use those words but he said: 'We have some difficulty here, there is a lack of connection,'" Blair said. "I thought, 'that's dreadful, what are we going to do about that?'"

London's Metropolitan Police said Saturday that it had reviewed the use of deadly force against suspected terrorists following Menezes' killing, and had made only minor changes.

A police spokeswoman declined to discuss details of the changes in Operation Kratos, the force's name for what British media call a "shoot to kill" policy.
