It seems worth calling out that if Larkin had "owned" the footage in the sense the article means, perhaps by recording it onto magnetic tape like a convenience store, he'd still be required to furnish it to the police. Deliberately destroying that tape, even in advance of the receipt of a warrant, can be actionable depending on your state's tampering and obstruction statutes.

So my take would be that it's not so much the "cloud" part of this problem as it is the "it's now convenient to have lots more cameras" part of it.
