About an hour before today's bomb scare at LAX, a man walked into the World Bank in Washington D.C. and went up to a security guard with a suspicious package claiming it was a bomb. The incident prompted nearby streets to close and people inside the bank were not allowed to leave. An hour later, a man walked up to an LA World Airports police officer and said he had a bomb in his backpack, which prompted the roads around LAX's terminal's to close. It was later found, like the incident in DC, that the bag did not have a bomb.
