Lone wolf terrorists pose new security threat

PARIS — The gunman had an arsenal that he claims to have stumbled upon in a park near the train station. Like three other men accused of drawing up failed plans for attacks in France recently, the suspect denied any links to terrorism, telling his lawyer he was homeless and only wanted to rob a train “to eat.”

Instead, the assault rifle jammed, and he was tackled and bound with a necktie by three Americans and a Briton who were celebrated Monday with France’s highest honor. Now, with many lives potentially saved on the high-speed train by quick-thinking and courageous passengers, the limits of a continent’s worth of security were thrown into relief by a lone attacker during a less-sophisticated act of violence.
