Japan's commuter trains can get a tad congested, offering an easy way for gropers to explain away their wandering hands. But an increasingly popular download called "Anti-Groping Appli" is giving women a new weapon in the war against fondling.
The offended party uses the app to flash a series of messages on her phone's screen. "Excuse me, did you just grope me?" might be followed up with "Shall we head to the police?" It's a way for users to confront the potential groper without hurling false accusations, and embarrassing a legitimately distracted co-commuter. Sound like a small market? It's not. In 2005, nearly 2,000 people were arrested for groping on Tokyo trains.—Gregory Mone
