^^bbmIs a search warrant required to gather location information from a service provider of an electronic device? Maybe not so much if the owner of the device allows it or the information matches the story? Just wondering.
Yes! A search warrant is now generally required to obtain cell phone tracking information pursuant to a 2018 Supreme Court ruling.
Prior to this ruling, investigators obtained records from a service provider by use of a court order that requires a lower standard than the "probable cause" needed to obtain a warrant.
Courts previously relied on a dated Supreme Court decision that ruled phone records were different than a phone conversation (requiring a search warrant) because people had no expectation of privacy in the records of calls made and kept by the phone company. Investigators had been treating cell tower records
as phone records.
The Supreme Court in recent years has acknowledged technology's effects on privacy. In 2014, Roberts also wrote the opinion that police must generally get a warrant to search the cellphones of people they arrest. Other items people carry with them may be looked at without a warrant, after an arrest.
Roberts said then that a cellphone is almost "a feature of human anatomy." On Friday, he returned to the metaphor to note that a phone "faithfully follows its owner beyond public thoroughfares and into private residences, doctor's offices, political headquarters, and other potentially revealing locales."
As a result, he said, "when the government tracks the location of a cell phone it achieves near perfect surveillance, as if it had attached an ankle monitor to the phone's user."
US Supreme Court rules police generally need a warrant to track cell phones — a big win for privacy activists
