At least nine states impose lifetime GPS monitoring on people with some categories of sex offenses. The current court case of Torry Grady in North Carolina is examining the constitutionality of this practice? Is is a violation of Fourth Amendment privacy rights? Can it be imposed in a civil proceeding? In the case of Jones v. the United States, the court decided that it was an invasion of privacy to install a GPS tracker on a vehicle that was parked on private property. Does this have any relevance to tracking human beings? Ultimately, this current case in North Carolina raises the fundamental issue behind this blog: what rights and entitlement do people who are on electronic monitoring because of involvement in the criminal justice system have? Also, is GPS monitoring a form of liberty deprivation or merely a condition like not being allowed to drink alcohol? Big questions as the use of GPS advances. Keep an eye on this case.
