These are certainly things that need to be balanced, but we already have a system for dealing with sensitive records. I think the ideal system goes like this: recording always on (keep working on battery issues), and anyone can request any video, but the police can ask a judge to withhold video of a sensitive nature.
The trouble with that idea is that some people are increasingly (and IMHO justifiably) skeptical about sensitive records being made or kept in the first place. Merely having some system for managing such records in accordance with whatever rules apply this week is not sufficient to retain the confidence of those people.
There will be mistakes. There will be leaks. There will be abuses. The possibility or likelihood of these things happening will surely have a chilling effect, even if serious problems are rare in practice.
