"Massachusetts Lieutenant Governor hailed the signing of legislation that authorizes courts to require domestic abusers who violate existing restraining orders to wear a GPS tracking device. These devices will automatically notify the authorities and the victims should an offender enter geographic "exclusion zones" set by the court. Offenders with the financial means will also be responsible for the expense of the GPS bracelet, which is estimated to cost $10 per person per day."
