Supreme Court Hears Arguments in Carpenter v. United States

By Ken Wallentine

Carpenter v. United States, U.S., No. 16-402, argued November 29, 2017

Justice Neil M. Gorsuch took center stage with his robust questions from the bench during arguments in the Carpenter v. United States case, the one likely to determine whether the government must obtain a warrant for historical cellphone location records from mobile phone service providers. Present law requires only an order issued under the Stored Communications Act. Such orders require only reasonable suspicion that a crime has taken place, not the probable cause standard required for warrants.

Justice Gorsuch suggested that the government is far astray of the Founding Father’s view of property rights. He quipped, “You know, John Adams said one of the reasons for the war was the use by the government of third parties to obtain information.” Justice Gorsuch was referring to Writs of Assistance, which dramatically differ from orders for historical cell site location information. The Writs of Assistance empowered British troops, officials and loyal sympathizers to enter private homes and conduct broad searches. Notwithstanding, it seems clear that Justice Gorsuch favors a “property interest” approach to Fourth Amendment analysis, rather than the “expectation of privacy” analytical model that has held fast for five decades, ever since the Supreme Court’s ruling in Katz v. United States (389 U.S. 347 (1967)).

But the tension between the two analyses dates back even further. During Prohibition, Roy Olmstead and approximately 50 others were involved in a massive bootlegging operation. Federal agents listened in on their telephone calls for months, gathering enough evidence for numerous arrests and raids. In Olmstead v. United States (277 U.S. 438 (1928)), the Court held that the warrantless wiretapping was permissible because the agents didn’t physically trespass on Olmstead’s property to eavesdrop.

Nearly 40 years later, the Court’s decision in Katz marked a sharp turn from years of precedent focusing on whether officers committed a physical trespass to gather evidence. Charles Katz made his living placing bets on basketball games across the nation, in violation of federal law prohibiting interstate gambling. To avoid the possibility of the FBI tapping his phone, Katz placed his bets in phone calls made from a series of public telephone booths along Sunset Boulevard in Los Angeles. The agents believed their wiretapping of a public phone was lawful. The Court disagreed, abandoning its “trespass doctrine” analysis and ruling that wiretapping counts as a search (physical intrusion is not necessary). In the decision, Justice Potter Stewart famously wrote that the Fourth Amendment “protects people, not places.”

More recently, in United States v. Jones (132 S.Ct. 945 (2012)), the Supreme Court held that installing a GPS tracking device to monitor Jones’ vehicle movements constitutes a search under the Fourth Amendment. The Court hearkened to a property rights analysis, holding that officers committed a trespass against Jones’ “personal effects.”

In the Carpenter arguments, Justice Elena Kagan queried whether the Jones holding should not directly lead to a similar ruling for historical cell site location information. After all, whether it is a GPS transmitter or a mobile phone, the pertinent information is the location data. The difference, of course, is that Carpenter voluntarily shared his location data with a third party—his mobile phone service provider. Much of the questioning and briefing concerns the Court’s holdings in United States v. Miller (425 U.S. 435 (1976)) and Smith v. Maryland (442 U.S. 735 (1979)), which held that people do not have a reasonable expectation of privacy in bank records (Miller) and pen register record of numbers dialed (Smith) when such records are disclosed to third parties. The Court’s decision in Carpenter v. United States may well signal the death of the third-party doctrine.

At the end of the day, the Court’s ruling will impact you and me far more than Carpenter. Carpenter is serving a 116-year prison term for his eight robbery convictions. Justice Alito asked, “Is any of this going to do any good? […] Is [Carpenter] going to get anything suppressed?” It is almost certain that the “good faith” exception to the exclusionary rule will prevent suppression of any of the evidence against Carpenter (the good faith doctrine was recognized in United States v. Leon, 468 U.S. 897 (1984)). Because the investigators used a court order to obtain Carpenter’s phone records, Carpenter can’t claim bad faith by the investigators, even if he “wins” his case at the Supreme Court.

Carpenter v. United States not only may upend the third-party doctrine, but the Court may move even closer to a strong property rights analytical model for digital privacy. The Court may decide that the Fourth Amendment protects people and places, particularly cyberplaces. The ripples of such a move would be felt for years to come as police develop investigative methods to challenge the ever-changing technology used for criminal purposes.

Northampton (PA) Department of Corrections

“It came down to three main factors for us: safety, time and efficiency. This is a way to protect  the staff, public and inmates in the best interest of all.”

Major Jeff Fox
Vigo County (IN) Sheriff's Office

“Lexipol’s Implementation Services program was key to getting our manuals off the shelf. If it weren’t for that, we wouldn’t be implemented today. Departments should recognize their limitations and realize that they likely don’t have the resources to do it on their own. Implementation Services is key to getting it done.”

Chief Deputy Ray Saylo
Carson City (NV) Sheriff's Office

"It’s a huge priority of this administration to teach policy to our sergeants, and Lexipol’s Daily Training Bulletins help us do that. We are constantly drilling into them that policy will protect them as an individual officer. If they ensure that their people are following policy, even if they’re sued, they will be OK.”

Sgt. Bryan Ward
Cumberland County (PA) Sheriff's Office

"Calling Lexipol an insurance policy doesn’t do it justice, because it doesn’t capture the enormous power that partnering with Lexipol provides.”

Chief Deputy Klint Anderson
Weber County (UT) Sheriff's Office

“We spent a considerable amount of money and effort trying to develop and maintain comprehensive and legally based policies and procedures. Lexipol has relieved us of that burden and provided us with a policy system that we have great confidence in and that we can tailor to suit our particular goals and community standards.”

Sheriff Blaine Breshears
Morgan County (UT) Sheriff's Office

“We had a use of force lawsuit, and as soon as the attorneys discovered that we have Lexipol, they said, ‘We won’t have an issue there.’ Our policies were never in question.”

Lt. Craig Capps
White County (TN) Sheriff's Office

"I would recommend Lexipol to any law enforcement agency, whether three-person or 2,000-person—it makes no difference. The program works.”

Chief John Defore
Hiawatha, KS

“By offering 365 daily training bulletins to my officers, I am saving far more than the cost of the software every year. In fact, I was able to show my commissioners a cost savings by utilizing Lexipol for our policy and policy training needs.”

Captain Jeff Schneider
Yakima (WA) Police Department

“KMS tracks and logs when people acknowledge and accept updates, which is very important, and it lets us track who isn’t getting the updates so we can give them the appropriate attention.”

Chief David Maine
The Village of Hunting Valley (OH) Police Department

“What we had before Lexipol had been around for years. It was like every other policy manual I had seen: It didn’t get the updates it needed. The Lexipol manual is a living, breathing document.”

Chief Deputy Lauren Osborne
Surry County (NC) Sheriff’s Office

“If there’s a change as a result of case law, or a procedure that needs to change, Lexipol does the legwork, sends it to us, we approve it and send it out to our people for acknowledgement—and it’s all documented.”

Sheriff Gerald Antinoro
Storey County (NV) Sheriff’s Office

“Lexipol is one of the best products I have seen in my 30+ years in law enforcement.”

Deputy Chief John McGinty
Simi Valley (CA) Police Department

“You get sued for your policies or you get sued for your actions, or both. You can only do so much about actions. But having Lexipol gives me confidence that if we draw a lawsuit, our policies won’t come under attack.”

Chief Kelly Stillman
Rocky River (OH) Police Department

“I can’t say enough about the positives from a chief’s perspective. I don’t know why everyone isn’t with Lexipol.”

Chief Jeff Wilson
Orofino (ID) Police Department

“The Lexipol Policy Manual is easy to use, it’s convenient and you have peace of mind knowing that you have a thorough manual that is going to stand up to any challenge the agency may face.”

Chief Ralph Maher
Oak Creek (CO) Police Department

“With Lexipol, I know our policy manual is going to be up to date. I can turn my back on it today and tomorrow there will be any needed updates waiting for me. That allows me to focus on some of the other things I have to do as a chief.”

Chief Steven Vaccaro
Mokena (IL) Police Department

“If you compare Lexipol to other policy providers, Lexipol is the only one that has policy that has been vetted by other chiefs, industry experts and lawyers. All you have to do is tailor the policies to your agency’s needs.”

Commander Leslie Burns
Mercer Island (WA) Police Department

“Lexipol provides a huge advantage for agencies pursuing accreditation. The tools take about 60% of the difficulty out of the accreditation process. If you want to be accredited, this is the way to do it.”

Deputy Chief Robin Passwater
Kankakee (IL) Police Department

“If you don’t have Lexipol, even with a full-time person dedicated to policy, there’s almost no way you can keep updated on all the laws and also have the training component. It’s an excellent system.”

Assistant Chief Bill Holmer
Glen Ellyn (IL) Police Department

“It’s a no-brainer for me. Someone is watching for changes to laws for me, and then tweaking the content based on those changes or updates in best practices.”

Lt. Ed Alvarez
Bay Area Rapid Transit (BART) (CA) Police Department

“I like the mobile app because it tells me no matter where I am when I have updates to complete or when people take the DTBs. No matter where I am, I have access. The officers can get real-time updates. Everything is at their fingertips, any time.”

Chief Greg Knott
Basalt (CO) Police Department

“Lexipol gives you peace of mind because the policies that you’re implementing have been reviewed by professionals in the field and by attorneys—not just your agency’s legal counsel.”

Chief Corry Blount
Bartonville (TX) Police Department

“I feel comfortable that when we issue a policy, it covers what it needs to cover. It’s the most comprehensive policy content I’ve used in my career.”

Lt. Victor Pecoraro
Auburn (CA) Police Department

“The updates are super easy because you can pop them open, see the redline versions and be able to edit it on the fly. Once I learned I could do that, I was excited.”

Chief Joseph Morris
Arapahoe Community College (CO) Police Department

“Officers are not infallible. We have limited memories like everyone else. Working under stress presents more challenges. There are times we need to access policies in the field so we are comfortable in our decision making. The mobile application has been great for this!”

Captain Jesus Ochoa
Coronado (CA) Police Department

“Knowing that Lexipol is keeping our policies current means that there isn’t something else for us to worry about. We can focus on our jobs. That definitely gives us peace of mind.”

Chief Steven Vaccaro
Mokena (IL) Police Department

“If you compare Lexipol to other policy providers, Lexipol is the only one that has policy that has been vetted by other chiefs, industry experts and lawyers. All you have to do is tailor the policies to your agency’s needs.”
