Internet porn at the library: A solution

Policing the browsing habits of those shameless enough to wack off in public is always going to be a small portion of a public librarian's job. The solution to this is simple. Provide a few computers in the library that are housed inside a plastic cubicle similar to a porta-jon. Let the weirdos and freaks go in there, do what they do and then leave. Once the room is clear jets of warm soapy water saturate the interior and then it's ready for the next homeless child molester. Security problems at the library will decrease dramatically and everyone is happy. It's so simple I can't believe it hasn't been implemented yet.
