GPS monitoring of batterers appears to be an ingenious solution to one of the major flaws of the current domestic violence protective order system. What makes GPS monitoring so attractive in the case of batterers and other criminals should make it equally attractive in the case of sex offenders. Although GPS monitoring has been questioned as potentially unconstitutional as applied to sex offenders, when individually tailored, it may prove to be an effective solution to the problem of monitoring sex offenders. In the future, states and municipalities would do their citizens a service by reflecting on the lessons of GPS monitoring of batterers when considering alternatives to residency restrictions and other measures aimed at monitoring sex offenders.
