The home owner could have stepped out and messing with cops is generally not the smart move. The home owner could have backed down but as with Ronin's story they don't always. I would also say we are not free if as citizens we are always expected to be the ones to backdown when confronted by authority. There are extreme cases like Ruby Ridge and Waco and smaller like Ronin's mom. We know how those turned out. The right answer is that unless the cop knows 100% somebody is in danger they should expect to backdown. That does not mean leave just backoff and get a judicial review if the citizen is pushing their rights. They hear a scream, go get'em. Other than that backoff, you have control of the perimeter if that is warranted. If I can't be in control of my own home what are we saying that this is a free country.
