Auryn saidI have a reasonable expectation of privacy to eliminate yesterdays meal, when in a public restroom. If I want privacy, I can get a motel room or take the person home or to a private location, not have sex in a room where minors and people (of all sexual orientations) that don't want or need to participate in what I'm doing can hear or see.
Is this to imply that when you are relieving yourself in the bathroom at the Mall that others may join you in your stall to watch you or to also relieve themselves in your commode?
The point is expectation of privacy, not definition of private property. The court established that you do indeed have an expectation of privacy in a public bathroom stall.
To further complement that, your argument that minors and other people of all orientations would be participating in the sexual intercourse within the stall decidedly thin. At the worst you may overhear some sounds and you may see feet. Unless the intercourse participants open the door or somehow manage to contort their bodies to expose genitalia under the stall door, then you're no more a participant to it than anyone else.
I don't feel it's appropriate for loud intercourse noises to come from the commode such that they can be heard.
That doesn't stop Billy Bob from laying one out with thunder and we don't arrest him for the loud flatulence. Nor does Jimmyjoe get arrested for a particularly fluid bomb run. Further, I have yet to see anyone get arrested for mephitic odor proliferation and trust me, if anyone should be arrested for anything occurring in the bathroom -- this should be at the top of the list.
