New: The military arm of the intelligence community has searched for information about Americans' movements without a warrant in a commercially available database of smartphone app locational data, per DIA memo for @RonWyden . https://www.nytimes.com/2021/01/22/us/politics/dia-surveillance-data.html
Building on previous good reporting on the topic of smartphone app makers selling their users' locational data via brokers and the US government buying and using it without warrants, including by @ByronTau @MHackman @Haleaziz @caro1inehaskins @josephfcox
Wyden is going to introduce a bill to close this loophole in post-Carpenter Fourth Amendment law. But look for it to get subsumed into the pending revival of the debate over the FISA reform/Patriot Act 215 bill that'd been on ice awaiting a new president. https://www.nytimes.com/2020/08/14/us/politics/mcconnell-fisa-bill.html
