If I were one of the people involved in inventing, developing, funding or launching GPS service, I’d be feeling very gratified right now (in addition to being rich). It’s sick that we need this kind of protection available, but it’s also exactly what technology is for. Good on them.

GPS devices have been used for years to monitor sex offenders. But technological advances have now made it possible for the systems to issue warnings by cell phone if the offender gets too close to a specific victim.

Massachusetts adopted a law last year that lets judges require electronic monitoring of people who violate personal protection orders. Michigan, Oklahoma and Hawaii followed suit this year with GPS laws, bringing to 11 the number of states with related measures, said Diane Rosenfeld, a lecturer at Harvard Law School who proposed the Massachusetts law.
