The Supreme Court! Indeed.
Like Reba said, it's a form of protection for the neighborhood kids. Nothing wrong with that. If that seems harsh or unfair, then perhaps the person in question should have thought about that beforehand. When someone victimizes other people, yeah, there tends to be some negative reaction and labeling in response to it. He gave up the right to privacy when he attacked his victim.
I have a "friend" whom asked to borrow 100 dollars. I can't, this is my bill money and it's been promised to so and so by this friday...Oh, I give you my word, I'll get it back to you friday morning so you can make your payment. I promise, I'll come through...well he didn't come through and I got late fees for it, I also tarnished my reputation by not keeping my word to them...So I got mad at him about it, not violent, just mad. I gave him a little crap about it because he made me look bad and cost me money, and I was trying to help...
You know what he did? He got mad at ME for being mad at him for not keeping his word. Said that I have no right to be mad at him, it wasn't his fault...he doesn't seem to understand that when you wrong someone, sometimes people have reactions to it. That's life. Don't do the crime if you can't do the time.
If I don't want to be labeled a sex offender, then maybe I shouldn't sexually offend? Maybe the guy that's mad about that sign will go ahead and sue someone for demeaning them? I have a right to keep my skeletons in the closet and not have them announced to the world...(Ha!). His victim had a right too once upon a time.
