They don't need a warrant. They only need to make a friendly administrative subpoena to Amazon, which will happily fork over the data without challenging the order, even if the owner has refused.
This is a good point, as well. Part of Ring's business model is integration with law enforcement. The incentives in place certainly don't align with user privacy.
This is a false story that relies on an incorrect statement from someone in the Fresno police department. Your own article contains this update:
> UPDATE 5:55pm ET: After we published our story, a representative from Ring responded to our request for comment to deny all allegations in the Government Technology report.
> "The reports that police can obtain any video from a Ring doorbell within 60 days is false," a spokesperson said. "Ring will not release customer information in response to government demands without a valid and binding legal demand properly served on us. Ring objects to overbroad or otherwise inappropriate demands as a matter of course. We are working with the Fresno County Sheriff's Office to ensure this is understood."
> "Ring will not release customer information in response to government demands without a valid and binding legal demand properly served on us."
Ring's own statement reflects what the OP stated: that Ring will turn over evidence when given a subpoena.
Ring also released a contradictory claim to what the police said Ring made available to them. Either the police are lying about a process they seem to know well and have used many times before, or Ring is lying in their statement to Ars.
I am primarily commenting on the "they don't need a warrant" bit, and the editorialized label of a "friendly administrative subpoena". A subpoena and warrant have a high legal bar, and the difference is who they are directed to. The way OP's comment is worded, it makes it seem like some significantly lesser bar than a warrant is being exercised. A subpoena still requires a court order, like a warrant! See https://legalbeagle.com/8676593-subpoena-vs-warrant.html.
Furthermore: Clearly, the Fresno police department person who spoke may not have understood the requirements for access or may not be aware of what prior actions (such as a subpoena) precipitated a release of video.
An administrative subpoena, as the name tells you, is not issued by a court and does not require a court to be involved. It's a police agency, acting on its own and without supervision, requesting documents believed to be related to a criminal case.
