Your “private individual” wording is carrying a lot of weight here. I wonder if Google knows where all the cops with Androids are? Or if Meta lets you bid for ad impressions from users “interested in law enforcement”

What if I wanted to record the cops to schedule my lemonade stand?

Basically, the answer to “Who gets to surveil?” is: Everyone but you

Start a site or a place where you can collect metrics and hand out cookies. Boom you're in the surveillance game. You can buy ad data, you can read census data, if you have the money it's all out there on the market. Hell if you don't have a conscience you can buy black market info.

You have to ask if you want more of that until we reach parity with Google and THE POLICE, or if you're reacting out of a sense of fairness that's taught to children.
