In 2007, a man named Juan Pineda-Moreno was suspected of purchasing products to grow Cannabis. Rather than put a GPS tracking device on his car and leaving it, they put several GPS devices on his car throughout a four month investigation. Most of the time his vehicle was on public property, but twice the car was in his driveway, so they entered his property at 4 to 5 in the morning to place it.

I'm aware that in United States v. Jones the Supreme Court ruled that police must obtain a warrant to use GPS devices. However, their conclusion had to do with how long the GPS was attached to Jones' car. In Pineda-Moreno's case, the GPS was used to follow him for short distances.

I cannot find any new information on this case past 2010. Can officers still use a GPS tracking device without a warrent?
