They're shootin' porn in that there van:

The Local 10 Problem Solvers discovered hardcore porn being shot, produced and distributed right here in South Florida. But the setting isn't a darkened movie set, it's a van that could be driving right next to you.

Yup, busybody South Florida newsies have finally sumbled across ye ol' BangBus. Or, perhaps more likely, some intern got busted at "Local 10s" offices browsing the grandaddy of all "porn-on-the-street" sites and called it "research" to save his job. It's the "oh-my-lawd, what shall we do?!?" breathlessness of the article that really clinches it. Must be a sweeps month or something.
