It's the non-invasive nature of facial recognition that presents a problem. If you install a camera above the entrance of a community center, then record everyone coming and going, you can identify who is attending what meeting and when. Perhaps someone walks in to a far right or a far left meeting group. Maybe an environmental action group. With that, 20 years later, you can destroy their career. They didn't sign anything, they didn't do anything, they were just witnessed going in and out. That's enough. Since the community center belongs to the government, it's just a matter of connecting things they already own, so it does not give the government anything it doesn't already have (or could have.) The problem is that people don't think that way. Nobody expects your movements to be associated with something undesirable in a decade or two, but it's happened before.
