Like license plate readers and facial recognition, you're out in the world without the expectation of privacy but I think for most people that feels different when a giant automated system is sucking everything up without recourse.
This particular article was about using Stringray with a warrant. I'm sure that the government is abusing Stingray but it'd be nice to have evidence first.
"In a recently-unsealed search warrant reviewed by Forbes, ICE used such a cell-site simulator in an attempt to track down an individual in Orem, Utah. The suspect had been ordered to leave the U.S. in 2023, but is believed to still be in the country. Investigators learned last month that before going to Utah, he’d escaped prison in Venezuela where he was serving a sentence for murder, according to the warrant. He’s also suspected of being linked to gang activity in the country, investigators said.
When the government got the target’s number, they first got a warrant to get its location. However, the trace wasn’t precise–it only told law enforcement that the target was somewhere in an area covering about 30 blocks. That led them to asking a court for a Stingray-type device to get an accurate location.
The warrant was issued at the end of last month and it’s not yet known if the fugitive was found."
