I&#x27;m 100% for lifetime GPS tracking of certain classes of criminals - It&#x27;s a far sight nicer than lifetime imprisonment, and that is a legitimate punishment.<p>But the EFF&#x27;s point here is solid: This wasn&#x27;t a punishment handed down as part of a sentence. This was added to someones sentence ex post facto, and that is not cool. It is fairly cut and dry; You only are sentenced according to the law at the time you committed the crime. Adding new punishments, no matter how well intentioned, is unconstitutional. I don&#x27;t even have to cite an amendment, it&#x27;s in article 1.
