I think this counts as a "general warrant", and is probably unconstitutional. To find which phones were in an area, the location history of everyone has to be searched. But warrants for everyone's location would be illegal, so if Google does that filtering, we kind of pretend it's legal. For now - I don't think this specific practice has been ruled on by the supreme court yet. As far as Google is concerned - I'd have them not store the data in the first place, and at a minimum have the spying be opt-in, instead of out. But I can't fault them for what they did after getting the warrant. Ideally they would try to fight it and get a supreme court ruling, but that's squarely in the good bucket. As it stands, the best I can hope from them is to be neutral, or at least not too evil.
