The core point that everyone needs to understand here is that ALPR is only a thing because technology sucked until now. Reading a license plate, something designed to be identified easily, took off when the tech got reasonably good enough. But facial recognition and general object recognition is getting to that point now too. If we don't stop ALPR, now, we will have constant track databases on people (if we don't already) in the future because the argument is essentially the same with only technology holding it back. This isn't a slippery slope. Fight this now.
