There's an annoying thought. Amazon could be providing a live feed of every ring device directly to an aggregated intelligence data center, while being legally prevented from revealing that fact by a national security letter. Seems inevitable, and anybody buying a ring device should assume it as likely.

Imagine the boon of having indexed facial, gait and voice recognition feeds recorded and stored for eternity covering a significant portion of residential and business locations.

Presumably this evidence will eventually come to light through court proceedings. I'm not talking like one huge case, but through thousands of inconsequential small cases where an effort is not made to hide the data origin.

Probably not. Great effort is made to hide the use if NSLs. Instead, they engage in "parallel construction" -- reverse engineering a different way of getting the evidence they've collected, so they can use the evidence in court without revealing the NSL.
