The bottom line of this story is that a man murdered his son. Premediated murder.

It really doesn't matter how old the son was, 15 or 51. What that man did was MURDER!

For heaven's sake people!!!! Do we believe in the rule of law or not?!?!?

Vigilanteism is NOT JUSTICE!!!

And don't give me any crap about how "you would feel differently if it was your daughter."

This is correct. I would feel differently. That is why laws are not based on emotions. That is why people have to recuse themselves from investigating, representing, judging, or serving on a jury when they have a personal connection to a case.

If that boy had molested my daughter, it is entirely possible that I might have harmed him (I can't picture cold-blooded murder, but you never know). Guess what? It would still be a crime. And I would still deserve to be arrested, and possibly convicted, and serve whatever sentence I was given.

This is how civilization works. If you don't like it, go live in the jungle.
