Dee, while I agree that the parents have a certain right to privacy, I don't blame speaking or anyone else for wanting some type of revenge. I'd love to kick the living crap out of the father and make the mother and sister watch.
When these people made a spectacle of their son in such a horrible way, they did, in some way, make their lives public. On this site, Topix or even the news shows, they laid i t out there in similar fashion to balloon boy a couple of years ago.
It's human nature to protect a child and to be repulsed by such actions as taken by this duo of morons. If you notice the sister didn't hang around long after the verbal beating she took.
The bible says we reap what we sew and in this case what was reaped was public outrage of an immoral and stupid act.
