But the cops can access the private land cameras. I would wager most small to conglomerate level business opt-in.
Last I checked the Lowes and Walmarts of the US share this data as its locks down shoplifters quicker.

Not for free, they can't. Flock isn't a charity. So your local cops can't get the data, but others can.
Police cannot access privately-owned Flock cameras unless the owners authorize them to do so, or a court orders it (in the same sense that a court can order access to any information on any device).
