I will never have one of those things in my home.
Can you imagine role playing? And Alexa calls the Cops because it thinks you are 'hurting' a woman?
Oh Stop! ... Please Don't! .. Oh my, I'm so helpless...Bang!, Bang!, Bang!, open up! Police!
And, I don't think the idea that someone was listening is too far fetched. Maybe not the NSA, but possibly someone associated with the Alexa product and network may have overheard what was going on. This is certainly going to hurt their sales numbers next quarter.
How does Alexa distinguish between 'real-life' or something playing on the TV, or stereo, or computer? How would it know if what it hears is really happening, unless it has eyes?
