A former United Nations weapons inspector who exchanged explicit online messages with a detective posing as a 15-year-old girl and then performed a sex act on himself in front of a webcam was sentenced Wednesday to at least 1 1/2 years in state prison.

Scott Ritter, 50, was taken into custody immediately after Monroe County Judge Jennifer Sibum sentenced him to 18 to 66 months behind bars. It was the second time in eight years that Ritter, of Delmar, N.Y., found himself in legal trouble for trying to lure underage girls into illicit sex.

Ritter, who maintains his behavior was shameful but not criminal, must register as a sex offender under Pennsylvania’s version of Megan’s Law.

"I had no business being in a chatroom on Feb. 7, 2009," Ritter told the court Wednesday. "I’ve asked my wife for forgiveness, and I’ve asked my daughters for forgiveness, and they have given it to me."
