Just theoretically if surveillance was good enough to catch every single crime in public, would this be "worth it"? As noted elsewhere, when football hooligans had cameras installed to identify them, they scouted out locations where there was not surveillance. Criminals would learn to commit their crimes under the cover of a roof or awning. This would make people safer from criminals, while making them less safe from the authorities.
