What's the difference between an Arab killing a Jew and a Jew killing an Arab in such a barbaric way? None. In both cases, the killer's home should be demolished. Yeah, the Israeli was hysterical with anger over the killing of the three Jewish boys, but that does not give him the right to pick out an Arab at random and murder him. It just doesn't.
Everyone involved in that despicable deed needs to be in prison for life and their homes demolished. If we don't make punishment equal for the same crimes, no matter who commits the crime, the State is unjust and that cannot be allowed to happen.
This way, everyone will know, Jew and Arab, that when a crime is committed, justice will be swift, fair, and equal under the law.
