Florida, Missouri, Ohio, and Oklahoma have passed laws that require lifetime monitoring of some convicted sex offenders after they have been released from prison. The offenders must wear electronic ankle bracelets and stay close to small GPS transmitters, which can be carried on a belt or in a purse. Computers monitor the GPS signals and alert law enforcement officials if the offenders venture too close to a school or other off-limits area. Police interested in the whereabouts of a monitored person can see his location, traveling direction, and speed plotted on a map. Do these laws represent an unacceptable weakening of personal privacy, or are they sensible public safety measures? Should they be repealed? Should people convicted of other crimes also be monitored for life? Would there be less crime if everyone in society were monitored?
