Here is aexcerpt that sheds light on this unfortunate situation that we now live in. It is a shame that we live in the most modern civilized country in the world and have this sort of crime. Punishment should be so severe that the thought of it would make someone on the edge of committing such crimes nauseous at the thought. That WOULD deter most! The rest need to be hunted down like the predators that they are and shot on site. At least there would not be the multitudes of repeat offenders. That would cull out this sort of sickness from our society and us law abiding citizens wouldn't have to pay the millions of dollars that it takes to incarcerate those scum of the earth.
