Yeah, your local friendly police officer isn't gonna do that.
They're gonna pay Anduril, Palantir, and a whole host of other business or consulting firms a ton of your money to do that.
The criticism that "it's technically too challenging for the police department therefore its sci-fi" is extremely silly given that the current article literally is about private companies that are building surveillance networks that they will then sell to the police.
Which makes the entire situation a lot worse.
