GPS-Enabled Criminals In Massachusetts

Fun at LinuxWorld writes "Following on the heels of California's plan to put GPS receivers in cars, Massachusetts wants to fit criminals who violation restraining orders with GPS devices. Wearing the device would be a condition of probation (meaning you can refuse, but then you get to serve your time in jail), and fines and punishments would be imposed if the person entered "restricted zones" (under the terms of the restraining order). With all the reports of GPS being used to restrict the rights of innocent people, is this any better? Will it fix the problem?"
