You don't need to search highly technical avenues to see GPS in application. I find that this technology is being increasingly used to solve social problems and purposes.

Prison officials in the suburb of San Bernardino, California have begun using global positioning system (GPS) anklets to track known gang members. Three prisoners were recently trapped with the help of GPS kits strapped on their clothes.

Under an arrangement between prison officials and San Bernardino, high-risk parolees known to belong to street gangs will be released from custody on the condition that they wear a GPS bracelet on their ankles at all times.

Many of you would agree that such an arrangement, if emulated at other places can help a lot towards bringing down crime rates. What do you say?
