Supreme Court Rules GPS Tracking Requires a Warrant

WASHINGTON (The Blaze/AP) — In a unanimous and precedent-setting ruling, the Supreme Court said Monday that police must get a search warrant before using GPS technology to track criminal suspects.
The GPS device helped authorities link Washington, D.C., nightclub owner Antoine Jones to a suburban house used to stash money and drugs. He was sentenced to life in prison before the appeals court overturned the conviction.
(Related: Check out this article about the case with a Blaze interview from a privacy expert.)
Associate Justice Antonin Scalia said that the government’s installation of a GPS device, and its use to monitor the vehicle’s movements, constitutes a search, meaning that a warrant is required.
“By attaching the device to the Jeep” that Jones was using, “officers encroached on a protected area,” Scalia wrote.
All nine justices agreed that the placement of the GPS on the Jeep violated the Fourth Amendment’s protection against unreasonable search and seizure.
Greg Nojeim, director of the Center for Democracy and Technology’s project on freedom, security and technology, said in an interview with The Blaze that the Supreme Court’s decision was “landmark”.
“It signals their willingness to protect privacy in the face of advancing technology,” Nojeim said.
Scalia wrote the main opinion of three in the case. He was joined by Chief Justice John Roberts and Justices Anthony Kennedy, Clarence Thomas and Sonia Sotomayor.
Wired has more from Scalia:
“We hold that the government’s installation of a GPS device on a target’s vehicle, and its use of that device to monitor the vehicle’s movements, constitutes a ‘search,’” Scalia wrote.
In a footnote, Scalia added that, “Whatever new methods of investigation may be devised, our task, at a minimum, is to decide whether the action in question would have constituted a ‘search’ within the original meaning of the Fourth Amendment. Where, as here, the government obtains information by physically intruding on a constitutionally protected area, such a search has undoubtedly occurred.”
Sotomayor also wrote one of the two concurring opinions that agreed with the outcome in the Jones case for different reasons.
Justice Samuel Alito also wrote a concurring opinion in which he said the court should have gone further and dealt with GPS tracking of wireless devices, like mobile phones. He was joined by Justices Ruth Bader Ginsburg, Stephen Breyer and Elena Kagan.
Here MSNBC describes difference in analysis by the justices that still ultimately lead them all to the same decision:

Nojeim also said that majority opinion of the Supreme Court placed an emphasis on that it was the pervasiveness of the tracking that stimulated the need for a warrant — not only the trespassing. Using this sentiment, he thinks that this could open the door for the potential of requiring a warrant on tracking cellphones as well, although this was not discussed by the high court.
A federal appeals court in Washington had overturned Jones’s drug conspiracy conviction because police did not have a warrant when they installed a GPS device on his vehicle and then tracked his movements for a month. The Supreme Court agreed with the appeals court. The case is U.S. v. Jones, 10-1259.
It is unclear if the precedent set today could affect other cases — like that of a California man who had two devices stuck under his vehicle — where police have used GPS tracking without a warrant. Nojeim said that in existing cases law enforcement will argue that it acted in good faith that a warrant wasn’t required.
Wired points out that the justices said “the present case does not require us to answer” if police use of GPS systems already installed by the owner would constitute trespassing and require a warrant. But, Nojeim points out, the Supreme Court decision does open the door for Congress to consider creating more specific legislation based on it.
“It laid down markers for Congress to consider,” Nojeim said.

Posted on January 23, 2012 at 3:03pmYou know what though, arresting TSA employees shouldn’t even be a part of our dialogue. The ones that deserve to be arrested are the legislature and their appointees that have repeatedly violated the Constitution. They all take an Oath to uphold the Constitution. The only way we can stop these types of things from happening in the future is to set the precedent of actually prosecuting them for violating their oath. I guarantee that if Americans held these people to their legal responsibilities to uphold the Constitution there would be a far more strict observance of the rule of law and a restored liberty to our country.

I shudder every time I am around a person dressed in a black robe. Shame on them!! Congress made at least 7 attempts to change the Constitutional requirement for a candidate to be a “natural born Citizen” beginning in 2003 which means Congress also know that Barack Hussein Obama was not eligible to be POTUS based upon that requirement otherwise they would have never gone though the exercise to change it avoiding the amendment process. Shame on them! Because of these cowards we now have a potential Constitutional crisis of the century on our hands. It will all come to light sometime during this Presidential campaign process.

Posted on January 23, 2012 at 2:20pmNope. I actually agree with it. If there is enough probable cause to warrant putting a tracker on a car, it should be good enough to get a search warrant to put the tracker on. I’m actually more comfortable knowing we will have the permission of the courts if we do it. Contrary to public opinion, cops dont just put trackers on everyday joes vehicle to see what he is doing. It’s usually a drug dealer and they are trying to find out where he lives, or where he stores his dope, etc. Does this post surprise you?

Sometimes they win and there is nothing I can do about it. But, they rarely quit being a crook and we eventually catch them at something else. We really only deal with about three percent of the population. We just deal with them over and over and over. Gets to the point that you know the names and birthdays of most of the people we deal with, because we deal with them so much. I must be honest, I don’t recall any of your posts, so I won’t make any comments there. The fact you answered my reply shows you are intelligent. The people on here that expect cops to be perfect, and then if they are not, advocate killing them and taking away all they have worked for, are the ignorant ones.

I am informed where most are not in the area of violent crime statistics that are not made public. For example a nearby city has at, best in the past 20 years, 18% to court tally from reported. If people understood what that number meant there would be outcry. Yes, I would agree that it’s the same ones over and over again for the most part and have not figured out why “judges” let some of them out when they know there going to see them in less than a month, again and again and again for the same stupid stuff. Must be the insanity rule.
I’ve witness “investigators” that use, how should I describe it, less than optimal methods on those that are clearly innocent of any crime and have witness locals tell military that there license is invalid because its from out of state, what is worse is they actually believe it. I’ve seen elected “officers” that are no better than the common thugs. If you’ve been in for anytime, you know there are good and then there are extremely bad, and then you have the “just dead weight”. The ones that I have know that are good, well, they really are not focused upon if you know what I mean.

Posted on January 24, 2012 at 2:14amYou local state, county and city cops have NOTHING to do with the Patriot Act. That’s a federal act. The Feds are generally bozos. And FYI, yes, cops write search warrants, which a judges reviews before signing to make sure it is legal. If there is a valid warrant, then there is no violation of the 4th amendment. 4th amendment doesn’t protect you from ANY search and seizures, just illegal ones. And no, you don’t get to decide which ones are legal. That’s why we have courts.
