A policeman (L) walks across the forecourt of Buckingham Palace in central London April 6, 2014. Local media reported that on Friday a Guardman left his post and pointed a bayonet secured to the tip of his rifle at a member of the public, when a man would not stop shouting at a police officer on duty on the gates outside Buckingham Palace.
