"Albert Gidari, director of privacy at the Stanford Center for Internet and Society, also thinks that criminal implications of a device like Echo, given the current technological constraints, are flimsy. But larger concerns come into play in a constantly mic’d up world.
“We all agree that if someone says, ‘Alexa, how do I wash the blood from my hot tub?’ then, yeah, the police would get a warrant,” Gidari said. A bigger problem, in his mind, is that users may not be aware of how to prevent Amazon, Google, and other companies from collecting more information than they would want tech services to be able to access."
