The police following one person’s car isn’t unconstitutional, but following everyone’s cars very much is. The IJ press release mentions this: the 4th Circuit (which covers Virginia) ruled several years ago that Baltimore’s near-continuous aerial surveillance was unconstitutional in part because it “ transcends mere augmentation of ordinary police capabilities.” I think there’s an entirely reasonable argument to be made that what the City of Norfolk is doing by contracting Flock to create a database of where every car has been for the past 30 days similarly crosses that line.
