Homes might be an exception, I don't know, but I'm of the impression it's routine for police to get physical search warrants with nondisclosure orders attached.

Yes for sure. Only homes are exempt. Which is why I originally said it should be treated as though it’s still in your home.

Right, and my point was, your proposal would proscribe large classes of common law enforcement searches. I'm stipulating the homestead exemption you're talking about here (obvs. neither of us are lawyers), but, given that, you're saying it should be extended far, far outside of homes.

That’s exactly what I’m saying. :)

Are you a little concerned that by advocating a drastic change in policing extending far past ALPR cameras that you're creating room for proponents of the cameras to say that everyone who opposes them wants broadly to hamstring the police?

I watched ALPR proponents in Oak Park make exactly those kinds of arguments.
