I heard about those (probably-not-so-alleged) incidents at the time. The overpass rock throwing was a particularly bad one, too. I have a friend, a person who's far from your typical "square" who's a bit older than me and absolutely hates B&B because he knew lots of kids who emulated them and did stupid things, and it really bothered him at the time. That would probably be me if that had been my experience.
That said, I don't think it's fair to judge something by how some tiny cohort responds to it, especially when we're dealing with extremes like setting your house on fire or throwing rocks from an overpass. There may be an argument to be made that if you're setting your house on fire, maybe a television show wasn't the root problem?
