Using third party systems like Flock for warrantless police work has not been fully tested in courts yet. With the current SCOTUS, I fully expect them to find it constitutional somehow if it lands there.

You're betting that someone's going to get a jail sentence for this? Because I doubt it.

The real reason why these actions are rarely punisned is that their supervisors are mainly annoyed that they got caught, not by the act itself.

police often avoid jail for killing people, unlikely this results in anything more than a change of location
