This bears watching:
In what may be a first, police in Arkansas asked Amazon for recordings potentially made by an Echo device in connection with a murder investigation. Amazon declined to provide the data.
As Echo currently works it keeps less than 60 seconds of sound internally and only sends recordings to the cloud (Amazons servers do the voice recognition) after you get it’s attention with the word “Alexa”. This is probably an acceptable tradeoff for most people.
Still, it is easy to imagine government mandates for “updates” to selected users which enable the devices to send continuous sound to law enforcement. And of course the same could be said of any other sound or video recognition devices in your home such as Xbox.
