Is it OK to be a temporary transgender just to listen to a really hot woman urinate in the bathroom?

My of my cop buddies told me there's a new problem of perverted men staking out busy bathrooms in LGBT-friendly locations.

When they see a really, really hot woman go in, they pop on a wig (to claim to be transgender I guess) then follow them in, their smart phones recording the whole time. They take one of the neighboring stalls and record the sounds.

He said there is a fetish web site where pervs do this and then post the "sounds" online, including the video of the hot woman who went in.

I guess I am not surprised, but just stunned because he said there's not much they can do about it.

I have told my wife and daughters not to use public rest room any more.

It was bad enough when perverts were drilling holes in walls, but now they can just walk in and do what they want. Then probably whack off too, I'm guessing. (Maybe during, definitely after.)

What are the rules in society now? Does anything go as "normal" now? Can people do nothing to stop this?
