I heard on a talk show (it might have been Mike McConnell) that the restroom is 1) way out of the way for the gates Craig was using (maybe even in another terminal) and 2) a known homosexual meeting place.
Most stings like this aren't trying to get jail time for gays, their trying to make a reputation that the airport isn't a friendly place for that type of stuff. If you don't know whether the guy you're tapping your toe at is a cop or not, you're less likely to make a public nuisance of yourself.
You and Benard have good points.
I think it is high time for the GOP to shake out all this crap along with the RINOS. I too think the Dims will try and make as much hay off this as they can. Hopefully it will have died down sufficiently prior to 08 lections.
