It was Bastille Day on the French Riviera.
A lawyer was strolling with her mother, friends and a colleague along the beachfront boulevard in Nice to celebrate France's national day. Four young sisters from Poland had spent a day of sightseeing. Two Russian students were on a summer break. And a Texas family, on vacation with young children, was taking in some of Europe’s classic sights. The bright lights of the packed boardwalk glittered along the bay like a string of stars.
