I don't think that police should be allowed to ask camera owners to voluntarily hand over footage, even if they would be willing to. That just allows them to privatize the mechanism of surveillance, similar to using data brokers to get around warrant requirements. Instead, I think that even where camera owners would willingly hand over footage, the state should still be required to obtain a warrant for said footage in order to preserve legal safeguards around evidence collection.
