“American taxpayers pay to be spied upon. That’s one takeaway from new documents obtained by the American Civil Liberties Union (ACLU), which has been examining how federal agents spent millions to purchase massive troves of cellphone location data and dodge Fourth Amendment requirements.
As part of a lawsuit against the Department of Homeland Security (DHS), the ACLU obtained thousands of previously unreleased records showing how DHS agencies—including Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE)—are purchasing and accessing “huge volumes of people’s cell phone location information quietly extracted from smartphone apps.”
These agencies are “sidestepping our Fourth Amendment right against unreasonable government searches and seizures,” suggests the ACLU.
In 2018, the U.S. Supreme Court held (in Carpenter v. United States) that under the Fourth Amendment, law enforcement must have a warrant before accessing a suspect’s phone location data from cellular service providers. But federal authorities have been getting around this by purchasing aggregated cellphone location data from data broker firms like Venntel and Babel Street. And they’re spending millions of taxpayer dollars doing it.”
