GPS for child molesters in Wisconsin.

As Wisconsin gets tougher on laws pertaining to sex offenders and child molesters, they recently developed a pretty interesting way of tracking and monitoring convicted child molesters.

Wisconsin has enacted a law that requires paroled child molesters to wear a Global Positioning System tracking device for at least 20 years.
“Expanded GPS will help law enforcement know exactly where these people are every minute of every day,” said Gov. Jim Doyle as he signed the bill into law Monday in Madison.
Under the system, warnings would be issued if a sex offender gets near a school, park or other places frequented by children, the Milwaukee Journal Sentinel reported Tuesday.

This is an interesting idea, but a little creepy. Like let’s not try and help rehabilitate your disorder, instead perpetuate it with extensive monitoring. But then again, I would want to know if there are child molesters hanging out around the elementary school that I work in.
Thoughts?
