I didn't watch. I am trying to avoid watching videos like this. It does nothing good for the mind.
With that said, overseas countries are pretty brutal in how they handle stuff like this.
Just go to a sexual offenders registry list and look for sexual offenders in your area--if you live in a major city, you will see how many sexual offenders actually live around you. Its quite disturbing. The US system is pretty shitty with stuff like this--child molesters get the bare minimum of sentences.
