Dick was commander of Operation Kratos, and in the immediate aftermath of 21 July 2005 London bombings, she was the gold commander in the control room during the operation which led to the police fatally shooting Jean Charles de Menezes, an innocent Brazilian man who had been wrongly identified as a potential suicide bomber. In a 2008 statement to the inquest investigating de Menezes's death, Dick expressed deep personal regret over de Menezes' death, but said, "If you ask me whether I think anybody did anything wrong or unreasonable on the operation, I don't think they did." The inquest jury recorded an open verdict. In a separate trial, the Met was found to have committed catastrophic errors that had led to the de Menezes's death, but Dick was cleared of any "personal culpability" for the tragedy. The affair nevertheless almost derailed Dick's career. In 2019, Dick said, "The events of that day stay with one; I think about it quite often. It was a traumatic period. It was an awful time for so many people, obviously and most of all Jean Charles's family, the people who were there when it happened, the firearms officers, the surveillance officers." De Menezes's family opposed Dick's later appointment as Met commissioner.
