Tokyo police are taking 3D mugshots of suspects

They'll help catch crooks spotted on camera at odd angles.

Security camera footage isn't always that useful for identifying suspects, even if you know who it's likely to be. What good is a mugshot when video shows the crook's head tilted down? Tokyo's Metropolitan Police Department has an answer. As of April, all of its 102 stations will start taking 3D mugshots that let them compare faces, regardless of the angle. Ideally, this will help arrest suspects that much faster -- police won't have to guess based on plain old photos, or ask for specialized gear to be shipped across the city or country. The 2D pictures aren't going away, but officers will soon have one more tool under their belts.
