The deadly New Year's Day attack was in the forefront of the city's offical Kings' Day event that begins the Carnival season.

The blame game has started with the Bourbon Street terrorist attack in New Orleans. Why it matters: Officials are seeking answers to how someone could plow a truck through the city's most famous street when millions have been spent to keep it safe.

For decades, it was well-known that Bourbon Street and the French Quarter were prime targets for terrorist attacks. It was also known for years that the security measures in place for these areas were inadequate to prevent such an attack.
