Criminals have long been fascinating. We sit glued to the TV as we watch a car chase or a high-profile trial, and even before television, the public loved to hear about the exploits of Depression-era gangsters or Wild West desperados. Just as interesting are the feds and the gunslingers who bring them to justice. As much as we might cheer for a charming bank robber, we love watching the law prevail. If you like cops and robbers, too, you'll love this photo gallery of some of the very most famous.
