GPS offenders?

have you heard about the new gps sneakers? i was thinking, the government should inject offenders with gps chips so their movements can be monitored. if a child went missing the offenders who were in the area could be checked on. they could make sure they don't go near school and they wouldn't be able to move and live unregistered in an unknowing community. there has been tons of research that suggests pedophiles cannot be cured and will always want to reoffend. so i think if they were constantly being monitored the chance of reoffending would be extremely low. about their rights, i think the inncoent children and people of the united states have the right ro be protected from them. these chips cold be considered protection for them too so they couldn't be falsely charged for a crime they didn't commit and they would be very apprehensive to reoffend and knowing that that is not an option more of them may reach out for psychological help (such as counseling). what do you think?
