If only France had enacted common sense gun control measures to prevent this from happening!
Was in Paris last week. My hotel was one block from the Champs Elysees at the Arc de Triomphe. All train stations, the airport, some subway stations and The Eiffel Tower were being patrolled by multiple 3 or 4 man security details armed with assault weapons. Saw no such patrols on the Champs Elysees. They take seem to be taking the threat seriously.
