We have an odd kind of expectation of privacy even in public places. I'm not saying we don't; I'm just pointing out that the expectation strikes me as not obvious. The Fourth Amendment calls out "their persons, houses, papers, and effects", which notably omits anything outside your immediate control.
The expectation comes from a pre-technological age, and I certainly don't fault the Fourth Amendment for failing to see how technology would change the ways in which we expect to be private even in public. But I do think it ends up calling for a recalibration of both the law and our expectations.
Ideally, I'd like to see that codified in a new amendment. Unfortunately, given that even simple, popular legislation seems impossible to pass, I can't imagine getting agreement on something with even the faintest whiff of controversy past the rather higher bar of a Constitutional amendment. So I'd be happy for a decent national conversation on the topic.
Personally, I wouldn't have thought that the law extended to an expectation of privacy on your front lawn, since you already expect your neighbors to be watching. It's interesting to see a court disagree. I wouldn't be surprised if this is overturned at a higher level, though unfortunately, at this point I've given up thinking of the Supreme Court as anything other than an ideology engine, so really just figure out which side is which and assume that it'll go that way.
