Amazon has come out an officially repeated the FACT that these things can't call 911, but these stories persist. A sheriff's office even kept insisting they were called by an Echo: THEY DON'T DO THAT! So: worry about them listening 24/7. I'll worry about credulously believing internet tripe. Was the battered wife's name Alexa or Ok, Google in all these supposed instances? Even if they could call 911, they wouldn't trigger without their key words.
