Only sharing specific clips is opt-in¹, but the program and its notifications are on by default. Maybe not surprisingly, consumers aren't asked if they want to participate, and the option is buried enough that most people will never see it.

¹ I'm being generous here. Police can still obtain Ring footage via warrants or "emergency" requests that don’t involve the user choosing to share anything.

So your concern here is spam of unsolicited requests from LE to consider sharing data related to some local event?
