I can imagine a scenario: A dumb-box is put in a squad car that can run queries specific to a person. You get pulled over, give the cop some lip for harassing you over your license plate expiration (the new sticker is in the mail). The cop goes back and uses the dumb-box to pull up 10 mile areas around a major crime and you happened to be in one of them. Now you're in the back of the squad car to be "interviewed" (read: assaulted) over an alleged association with a crime. Doesn't matter if within that 10 miles is a grocery store and a bank.
It doesn't end with the police though. This is enabled because we willfully carry tracking devices everywhere we go. It's the greatest slight of hand ever pulled by the CIA and FBI. So great in fact I doubt the legend of corruption Hoover could imagine it. Some of us avoid the obvious traps like social media and some of us even have hardware switches on our phones. The vast, vast majority of Americans are beacons brighter than the sun with Tiktok (CCP intelligence app), Facebook (US intelligence app), etc.
Privacy advocates have been shouting from the rooftops for two decades now about the future of spying and we gave up privacy for convenience and even paid for it. In some sense, we deserve exactly what we paid for.
