         | I'm not familiar with Nest, if you don't have a subscription to

         | seconds to bring it up in the app, can you scroll back and see
         | those 5 seconds? Or is it literally a feed from the camera to
         | the app over bluetooth? Probably not. The video stream probably
         | gets sent to some backend system and, while she didn't pay for
         | storage, it probably persists for a few hours to days in cache.

         | Here I was thinking the primary purpose was to see who's at the

         | Not everything needs to be a conspiracy. These devices are
         | useful and practical and have value.
         | 
         | Also, lest it get lost in the chorus of voices telling us to
         | throw these things out: the actual news here is that the device
         | appears to have provided an actual evidentiary lead in the
         | investigation of an actual (and horrifying) crime. That has
         | value too, even if kidnappings are rare.

         | First off, it's not inexpensive. It's not a giant investment

       | Yes, storing customer data is what we'd expect from Google and

       | 
       | My hunch is that Google initially tried to play dumb to avoid
       | compliance, as to not reveal they do in fact retain customer
       | data. They had a plausible excuse as well -- the owner had no

       | at face value, since they parroted this explanation to the public

       | and only then was the footage released.

       | There are several reasons for that. The first is that you cannot

       | 
       | My guess is that they either went to Google to perhaps connect
       | the camera to a sandboxed testing rig that could extract locally-

       | read heads on the VCR's spinning drum. You could then process
