This is the infamous Tijuana mug shot. When authorities capture suspects here, the detainees are often paraded in front of news photographers. This typically involves a whole level of theatrics with the suspects being forced to stand before their stash of stolen goods or to wield the (presumably unloaded) weapons used to commit the crimes. Sometimes a weak smile emerges in the photos, but most of the time the suspects stare stone-like at the cameras in their awkward poses.
