When I first read about this happening I was shocked but when I read this article that indicated this man already had a history of violent crime including the death of his own son I became angry.
The obvious question for me is how an individual like this could still be walking free in our society? We simply cannot complain about all of the violent crime if we are actually facilitating it by letting these kinds of people loose back into society.
Mind you I am not in favor of capital punishment nor do I favor life incarceration on the tax payer's nickel. I really wish that we could bring back the practice of banishment where we strip them of their citizenship and simply kick them out of the country and let them sink or swim on their own. That way our society is rid of them and we as a nation don't have their blood on our hands either. Their fate from that point on is in their own hands.
I know that this sounds rather simplistic but sometimes the simplest solutions are the best ones. The problem is that in such a case you have to send them somewhere and most countries I know of really don't want our trash. Britain sent theirs to Australia when it was still a far off nearly unsettled frontier with only the indigenous native tribes there.
Alas we no longer have such places left as repositories for our criminal elements. Maybe we could use them as guinea pigs and send them to Mars to start a colony there. LOL Joking aside that really would be a better approach. If only we could find a place to send them we would be much better off socially and financially. Three time loser and you are gone.
