A French riot police officer patrols with the Eiffel Tower in the background as family members of police officers demonstrate in what they described as a march of support for all French security forces, in Paris, Saturday, April 22, 2017. The Saturday march comes just two days after the Champs Elysees attack in which a police officer was shot with two bullets to the head and two others were wounded before being able to kill the shooter.
