'Bubbles says loudly, "Camera networks on streets, Red moreso than anywhere else, are watching hugely packed streets. Think about whether your character is really hearing and seeing everything when one PC walks through what should have hundreds of ambient population. Thank you."'

Well, to solve that particular issue, why not have ambient message stating people of similar clothes going to random places to people watching cameras? As a way of showing that all shrouds, hoodies, whatever look alike when they're in hugely populated areas, pretty much sending them on wild goose chases.
Sometimes they luck out, sometimes they'd find nothing.
