The same arguments keep being repeated in these threads. They really need to be broken down into their separate issues. Otherwise it's like we are playing "rock-paper-scissors" -> rights of consenting adults, nuisance of this behavior in a public bathroom, Craig solicited the sex but didn't get caught carrying it out.
rock: I'm sure we all agree consenting adults should be able to have the sex of their choice.
paper: Is it or is it not private in a public bathroom and is it a nuisance crime to have sex in public bathrooms?
It may seem innocuous if you forget about the inadvertent consequences. Kids are going to use the bathroom, they are going to see the activity, condoms may be left around (and they could be anyway but lets not pretend having sex in the bathroom doesn't increase the likelihood), people obviously notice or they wouldn't be complaining, the perps are getting some of their jollies out of the danger of being noticed.
I would also add it is a public health problem having random sex encounters. It increases the risk of STDs including HIV and these guys are often married to unsuspecting partners. Risky sex can result in death from HIV and that includes innocent participants (namely the spouse).
scissors: Was the sting operation legit or entrapment? Did soliciting the sex cross the line or was more needed to constitute lewd behavior?
I think it's absurd to argue Craig was doing something else. And this kind of behavior includes the public sex. The legal standard is reasonable doubt and it is unreasonable to assume the gestures were anything but soliciting sex based on the fact there was a combination of gestures with no other reasonable explanation (wide stance is not reasonable*), and unreasonable based on the documentation by psychology researchers about this behavior to presume the sex was intended to be carried out somewhere besides in the bathroom.
Perhaps in this case the cop should have waited for more steps in the ritual to have occurred before making the arrest such as waiting for a more specific statement of intent. But frankly, arguing this point as if Craig's rights were denied is beyond what I think the ACLU should be concerned about. If all the worry is merely over a hasty judgment call, then a plausible alternative should be presented as to what else the stall peeking, foot tapping, foot bumping, stall divider rubbing ritual could have meant besides sex in the public bathroom.
If the ACLU is arguing men should be able to get it on in a public bathroom stall then they need to explain why that doesn't interfere with my rights as a parent to send a young child into that bathroom unaccompanied.
