WE HOLD NO BRIEF for "Debby Does Dallas" as a cinematic work of art, or for any of the other hard-core, triple-X-rated movies that are making the home-screen rounds via video cassettes these days. But thanks to blue-law mentalities in the suburbs, this dirty stuff has turned into a phantom commuter tax: sales and rentals in the District (add 6 percent sales tax, please) are healthy, if that's the word.

The most vigorous crackdown on video porno has been in Northern Virginia, where police and prosecutors have been citing "community standards" to distinguish between obscene and merely sexually suggestive home-fare. Nobody is quite sure how these "standards" should differ from one "community" to the next. But there was a time when suburbs were referred to as bedroom communities, and maybe now it's the city's turn.

But if it's back to blue laws, viewers should be given a chance to elect the censors--and throw them out if they call the shots wrong. And while they're at it, what about all those books in the libraries? Aren't the standards the same when what you see is what you get?.

Or is your home in fact your castle?
