At one time, I would have urged that as a remedy, but the thought patterns that accompany the acting out remain, and can probably erupt in other forms of assault and aberrant behavior. Still, it could be a start.
The best thing to do with what we now know is to isolate them from the rest of the population which modern thinkers are loath to do. My state, and others, have started enacting laws determining that they cannot live anywhere at all in some urban areas because of their proximity to day-care centers, schools, etc. They will undergo forced relocation. Then the people in the outlying areas will be stuck with them, and with the mobility of the population such as it is today, there's no guarantee they won't drive, hitchhike, walk, bike right back to where they can pick off another victim, so I don't particularly feel that children and other prospective targets would be safer under such a plan.
A case, probably several, will turn up again after all that effort, and it will be back to the drawing board, all because we don't want to lock them up.
Executing them is extreme, but there are times that is my knee-jerk reaction.
Absolutely correct! I have been telling the proponents of castration that for years. Making a molester incapable of getting a woodie changes nothing in their head. They will simply channel the aberrant sexual needs into other forms of abuse.
