All dragnet surveillance done by law enforcement or given to law enforcement by private entities should be public. (Targeted surveillance by law enforcement is a different thing.)
We should all be able to "profit" from this data collected about us. There are likely a ton of interesting applications that could come from this data.
I would much rather independently run a "track my stalker" application myself versus relying on law enforcement (who have no duty to protect the public in the US, per SCOTUS) to "protect" me, for example.
It might be that such a panopticon would be unpalatable to political leaders and, ideally, we'd see some action to tamp down the use of dragnet surveillance (and maybe even make it illegal).
