This from Wikipedia:
"Lowe gained notoriety in 1988 after a video of him having sex with two women, one of whom was underage, became public. He had met the women at a bar while in
Atlanta attending the 1988
Democratic National Convention, and later claimed that he didn't know one of them was underage, and that it was reasonable to assume that someone in a bar was of legal age. The video that was widely circulated was not the one with the underage girl and her lesbian hairdresser girlfriend but that of a threesome with a model called "Jennifer", a young friend called "Justin Morris" and the actor himself, shot in a hotel room in Paris. Lowe was sentenced to twenty hours of community service. He was later committed to a rehabilitation clinic for alcohol addiction."
So, there are apparently two videos out there with Lowe having sex with mulitple partners. While the second tape was more widely distributed, the first tape also made the rounds. The risk would be not knowing which one you might be watching until you've already started viewing it.
