I was watching the BBC report (live) on the journey of the King and Queen Consort from Westminster Hall to RAF Northolt when I was astonished to see someone jump out of his car (traffic in that lane was stationary at the time), run over to the royal car, take a photo, wave to the King then run back to his car. It could just as easily been a gun in his hand as a camera. Didn't anyone else notice this potential breach of security?
