I think your critique of police here is orthogonal to the privacy discussion, which affects everyone:

Imagine the danger and legitimate fear a stalking victim would face if there was a public real-time tracker for any license plate query you can imagine.

What if there was a book that listed everyone's phone numbers?

So, like, cops are currently doing?

Imagine the danger and legitimate fear a stalking victim would face if their stalker is a police officer with access to Flock.
