Hopefully, this isn't a new vertical for the U.S.

In Japan, there is apparently such an abundance of scum-bag men that the subways feel the need to install "anti-groping" cameras. I'm more than a little skeeved out by that. I will also refrain, for at least a day, from complaining about the male-dominated state of the security industry. Things, apparently, could be worse:
Japan's city trains are infamous for gropers, some of whom exchange tips on Internet forums on how to fondle women or try to sneak revealing photographs of them in a packed carriage. In 2001, Tokyo began running women-only carriages during rush hours. Tokyo police handle some 2,000 groping cases each year. More than 80 percent of women say they have been molested on trains, according to a survey by the non-profit Nippon Foundation.
