So I guess that means no claymores planted in the yard. Dang.

Seriously though, this is a real concern. How do you build a house that is raid proof but that can be accessed by the fire dept? Maybe we should push the context of the problem back a little bit and ask: how do we de-escalate the police state in the U.S.?

De-escalation is part of why I'd want that kind of camera system - the signs would serve a dual purpose, A) notifying and hopefully at least heavily clouding charges of "he had no legal right to record, we weren't in a public place, charge him with wiretapping" (I'm in Illinois which is an all-party-consent state) and B) putting police on notice that even if they aren't using body cameras (or they're prone to "malfunction") there will still be recordings.

Given the apparent change in officer behavior that accompanies body camera use, perhaps having explicitly noted video and audio surveillance disclosed in advance will serve a similar purpose.

It looks like this was overturned in 2014.

n.b. I learned about this in a recent episode of "The Good Wife". I am Canadian.

The relevant part in those cites is "public places" - previously it was illegal to record police even standing on the sidewalk. Technically a news crew doing "man on the street" interviews would have been required to stop if an officer showed up.

The scenario we're covering here is for police inside your house, which I'm pretty sure wouldn't be considered public.

Flood stilts seem like they would do a lot to complicate surprise entry.
