Actually, other than the rather absurd stretch that it should be treated the same as if the perverts had invited school children in to watch, pgyanke raised a pretty good point. If you open up your bedroom and expose the public to it and then engage in acts that would be considered lewd in public, then it is very easy to be "publically lewd in your own bedroom". If you don't believe this, try this little exercise and let us know how it works out: Buy a house right across the street from an elementary school with a front bedroom with great big bay windows. Open the drapes/blinds/shades so that the front bedroom is visible from the street (and school). At about 3:00 pm (or whenever school is letting out and the kiddies are waiting for their parents or the bus to pick them up) get naked and stand right in the big middle of those bay windows and pleasure yourself. I'll just bet you will find you can be charged and convicted of public lewdness (and even lewdness with a child or equivalent) right there in the "privacy" of your own bedroom.
Ahh, proof again that the exception proves the rule. Yes, you found a loophole. Just like I could invent a scenario in which you could be arrested for driving the speed limit.
Anyone remember that kind of thing happening just after they opened up the baseball stadium in Toronto that has the hotel attached?
