The former UN weapons inspector Scott Ritter has been convicted of unlawful contact with a minor for exchanging explicit messages in an online chat room with someone he believed to be a 15-year-old girl. Ritter, 49, exchanged messages with a detective posing as an underage girl and masturbated, even after the undercover officer stressed during the chat that he was a minor, Pennsylvania prosecutors said. A jury found Ritter guilty of a total of six counts including indecent exposure and criminal attempt to corrupt a minor.
