A little more Journalism 101 from ABC News: When you’re interviewing alleged prostitutes; when they’re charging that they had sex with a U.S. senator; when they make strange and impossible contentions about Internet searches; when they are speaking to the media for reasons that aren’t readily apparent and almost unfathomable; when they’re all essentially reading from the same script: If all of those conditions are met, then you may want to check whether they’ve given you their real names.

Check out the video below, as ABC News’s Brian Ross asks one of the women if she could produce ID. “No,” she replies.

A warning sign, perhaps?
