Justice Neil Gorsuch agreed with the majority\u2019s bottom line but not its reasoning.<\/span><\/p>\n<p><span>In dissent, Justice Samuel Alito wrote that the majority had destabilized the law in ways that \u201cwill send seismic waves through our Fourth Amendment doctrine,\u201d adding: \u201cI cannot support this irresponsible escapade.\u201d<\/span><\/p>\n<p><span>Justices Clarence Thomas and Amy Coney Barrett joined parts of Alito\u2019s dissent.<\/span><\/p>\n<p><span>In her majority opinion, Kagan grappled with how to apply the Fourth Amendment\u2019s traditional protections against unreasonable searches to rapidly changing technology that has made it easier for the police to scoop up vast amounts of data to assemble a detailed look at a person\u2019s movements and activities.<\/span><\/p>\n<p><span>It had been eight years since the court last took up a major case involving the expectations of privacy of the millions of people carrying cellphones in the digital age. In that 2018 case, the court ruled that the government generally needs a warrant to collect location data drawn from cell towers about customers of cellphone companies.<\/span><\/p>\n<p><span>The court has also limited the government\u2019s ability to use GPS devices to track suspects\u2019 movements, and it has required that law enforcement get a warrant to search individual cellphones.<\/span><\/p>\n<p><span>Monday\u2019s decision in Chatrie v. United States involved a broader kind of search. It involved Okello T. Chatrie, who was convicted in the 2019 armed robbery of a Virginia bank. Police used a geofence search to capture location data from all the cellphones in the vicinity of the bank for 30 minutes before and after the robbery, and identified Chatrie as a suspect. He challenged the search after his conviction.<\/span><\/p>\n<p>Read more <a href=\"https:\/\/bostonrelocationinsider.com\/?p=3894\">What the Supreme Court\u2019s ruling in the Cook case means for Federal Reserve independence<\/a><\/p>\n<p><span>In Chatrie\u2019s case, the government did obtain a warrant, but one that his lawyers said sought an overly broad set of data and violated the Fourth Amendment.<\/span><\/p>\n<p><span>The Justice Department told the justices that a warrant had not been needed at all to review anonymous location data.<\/span><\/p>\n<p><span>What the ruling will ultimately mean for Chatrie is unclear, but Alito predicted that \u201cnot one iota of the majority opinion will affect the outcome.\u201d<\/span><\/p>\n<p><span>Millions of Americans use a Google service known as \u201clocation history,\u201d which gathers data roughly every two minutes about where its users travel and when. That creates a powerful set of information law enforcement can use to try to solve crime.<\/span><\/p>\n<p><span>Unlike traditional warrants, which target an identified suspect based on probable cause that he or she has committed a crime, geofence warrants operate in reverse. Law enforcement draws a virtual fence, or boundary, around a geographic area where a crime has been committed and asks technology companies for data on every user whose device happened to be in the area during a particular time frame.<\/span><\/p>\n<p><span>Chatrie\u2019s lawyer argued to the court that a person\u2019s location history, which can be reviewed, edited and deleted, is akin to private property because the data is stored in a password-protected account. Even if Chatrie had agreed to share the information with Google, his lawyer said he had not agreed to share it with the government.<\/span><\/p>\n<p><span>The solicitor general\u2019s office countered that Chatrie had voluntarily shared his location data with Google. Similar to a person\u2019s bank or phone records, which are held by a business, the government argued that there is no expectation of privacy for information that someone chooses to share with a third party.<\/span><\/p>\n<p><span>Google says it stopped responding to geofence warrants last year, because the company no longer stores such data and instead keeps location data on each user\u2019s device. But law enforcement has made similar geofence requests of other tech companies, including Apple, Lyft, Snapchat, Uber, Microsoft, and Yahoo, meaning the Fourth Amendment questions before the justices have remained relevant.<\/span><\/p>\n<p>Read more <a href=\"https:\/\/bostonrelocationinsider.com\/?p=3892\">Supreme Court says Fed\u2019s Cook can keep her job for now, but it upholds other Trump firings<\/a><\/p>\n<p><span><i>This article originally appeared in <\/i><i>The New York Times<\/i><i>.<\/i><\/span><\/p>\n<\/div>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>WASHINGTON \u2014 When police officers sweep up location data from cellphone users near crime scenes, they must comply with the Fourth Amendment, the Supreme Court ruled Monday in a modest victory for privacy rights in the digital age.<\/p>\n","protected":false},"author":1,"featured_media":3897,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-3898","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-politics"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
