(Memphis) They sit atop squad cars and act like a few dozen eyes in the sky.
Using high-tech electronics to take in information about every single car they pass, squad car scanners alert officers to anything from if you're wanted to if you have an unpaid ticket.
The American Civil Liberties Union has found police officers across the country storing simple information, like days and times your car has been spotted by one of these squad car scanners, and storing your whereabouts for years.
“We would all be creeped out if a police officer followed us around, behind our car” said Brian Faughnan, with the ACLU. “That’s what this technology does.”
Memphis police say they only use the technology to spot things like stolen plates and known gang members, and they immediately erase everything.
Most drivers still don't like it, but say they don't expect much privacy these days.
“Privacy has been given up and we didn't know about it,” said Jamarious Carter.
“I don't mind, I haven't done anything. I understand what they're trying to do," said Chris McLaurin.
Faughnan says some rules need to be put in place, "There needs to be regulations to ensure that's what occurs and if some employee transgresses they can be held responsible."
