The issue, of course, isn't how cameras can be used to help apprehend criminals. It's that they can be abused by people who have access to them, in ways we haven't even imagined yet. People don't trust that appropriate safeguards are in place, and it's not clear how to defend against abuses, or that it's even possible. In a society that supposedly prioritizes liberty, privacy, and innocence until proven guilty, such technology should be treated with maximum suspicion.
