PHILADELPHIA AP – A longtime U.N. weapons inspector who blamed a 2001 sex-sting arrest on his criticism of the Iraq war has again been charged in an online child-sex case, and this time he was caught on camera.

Scott Ritter, 48, of Delmar, N.Y., engaged in a sexually graphic online chat with an undercover police officer posing as a 15-year-old girl nearly a year ago, police in northeastern Pennsylvania said. He then turned on a webcam and masturbated on camera, they charged.
