Thanks to everyone who read my post carefully and provided thoughtful responses.
I think that those who defend the kid's behavior as normal and are scornful of my "hand wringing" may have felt differently if they had actually seen the kid for themselves. I probably did a poor job of describing it, but his demeanor was distinctly odd.
As to property lines, all I can say is that in my neighborhood (like it or not, right or wrong) you simply do not cut across people's yards, climb their trees and lean on their houses without permission.
Well then I would say, go talk to his parents first before judging, AND why not be the first in your neighborhood to welcome and kids onto your property. Be the Kool-aide mom:)

And I meant to add, when you go talk to his parents, don't put them on the defensive. Just introduce yourself as just a person who is extending a welcoming hand, and wanting to meet the kids that roam the neighborhood.
