They had a case in Texas about that which set a precedent prior to the pedophile madness movement. There is a place near Austin where people swim called "hippie hollow". It is clothing optional. A woman used a telescope to see naked people from her home some outrageous distance away (it couldn't be seen with the ...naked eye). She sued, and lost, because the ruling was that if you have to employ technology to see something, you are the one seeking visual contact, not the naked person!

It would be hard to say that he intended to be discovered by the kids without more information about where he was and a tremendous amount of argument to support that motivation.

Going (how was "sneaking" determined?) into the boys locker room and undressing is a little harder to explain, but a mentally challenged person or someone who for some reason truly didn't understand what the facility was for and that they were not supposed to be there, might could do such a thing innocently.

The two incidents together certainly sound an alarm, but they don't justify horrendously Draconian response or vigilantism.

My argument is not that behavior like this should be ignored. There are indecency laws and other things available to place him under supervision and evaluate his behavior. If he is actually seeking to expose himself to children, then something has to be done to stop it. That may or may not involve institutionalizing the guy. There is a too much more we need to know about him. The two acts described here lead me to believe exactly what TChris has said. I sounds like he is mentally challenged, and may just need some counseling involving appropriate forms of sexual expression.

Imagine what it is like to be in a mental state that doesn't allow for any kind of intimate connection with other human beings, and not knowing or understanding anything about your own sexuality. The guy might just need a forum where he can safely explain his feelings and be taught how to manage those feelings without pissing people off.

Does he have the right to decline a psychiatric evaluation?  He apparently posed no immediate threat to anyone, even himself.  Weak grounds for arresting him or (forcibly) sending him to a psychiatric clinic.  

What if someone wanted to avoid a psychiatric evaluation because they didn't want to be "labeled" in a way that would affect them personally or professionally?  Could they opt to be charged criminally(trespassing) rather than be officially deigned a sexual offender?

I am impressed with the buzzard story, except for the fact that buzzards are only interested in carrion, not something or someone who is alive.

With that out of the way, as much progress as we have made in the area of mental health care and treatment, it seems that it is only less stigmatizing if you are reasonably well off - if you are poor or homeless - or uninsured - you may never get the kind of treatment that might help you be something other than poor and homeless.

This is not to say that a person with a mental illness cannot represent a danger to others, but it seems like we ought to be handling better those whose mental illness lands them in the criminal justice system - especially those who are not likely to have support of family or the means to access the best legal representation.

The man's behavior and bizarre responses to the kids and police suggest that he's plagued by an untreated mental illness. As is true of too many Americans who suffer from the twin menaces of poverty and mental illness, he'll probably be dealt with by the criminal justice system when he should be in the health care system.

Sure sounds like a screw is loose, but that ain't a crime.  Perhaps the authorities can point him towards a more secluded area not near a school to live out his weirdness.  Doesn't appear he's trying to hurt anybody...but even I'll admit ya can't have naked people hanging around a school, then you're begging to be dealt with...lets just hope not too harshly.
