First Osama bin Laden was killed in a Navy SEAL attack. Now, James “Whitey” Bulger has been captured in Santa Monica.

While some think the spots would be quickly filled — there are plenty of nasty criminals out there on the lam, aren’t there? — making the list is actually a long, complicated process. Field agents from the 56 FBI offices across the country nominate their most evil fugitives, and the final decision comes down only after a review from the top office.

The list started off as a publicity stunt, according to the FBI Web site. A journalist wanted to do a story on the “toughest” criminals in the United States and the FBI came up with some names. The response from the public made the agency realize that they ought to undertake the list as a real deal.

It’s been around since 1950, and of the 494 fugitives that have made the list, 464 have been apprehended or located. Bulger was the oldest one to make it. He was 69 when he was added in August 1999. He is now 81.
