Hill SecurityScreen-shot from security camera mounted on East Block shows Islamic terrorist Michael Zehaf-Bibeau (circled) running toward Centre Block on Parliament Hill, almost exactly nine years ago. Zehaf-Bibeau had just fatally shot Corporal Nathan Cirillo, a Canadian soldier and reservist on ceremonial sentry duty at the National War Memorial. He was later shot dead by the House of Commons Sergeant-at-Arms Kevin Vickers, a former RCMP officer.
