First, happy 2012 to everyone! :-)
Slashdot is running a discussion named Judge Doesn't Care About Supreme Court GPS Case.
Their summary: "The Supreme Court is currently deciding whether or not law enforcement needs a warrant before they put a GPS tracker on a person's car. A judge in St. Louis doesn't seem to care about that, though. He ruled last week (PDF) that the FBI didn't need a warrant to track the car of a state employee they suspected was collecting a paycheck without actually going to work. (Their suspicions were confirmed.) While in favor of corrupt government employees being caught, it's a bit disturbing that a federal judge would decide a warrant wasn't needed while the Supreme Court has said the issue is unclear."
