fine line, because tech companies want their smart speakers to be helpful assistance, not unwanted souksred to be one thank you very much paired with more, mark eiglarsh, . i'm fascinated by this, mark. because these devices are on and so many homes across america now, and amazon downloads the information and uses it for advertising purposes. so they have these recordings of what has been said. i talk to me about the prosecutor's desire to have this one and to have the information uploaded for them. >> i get their desire to want to get it. they need to prove a brutal double homicide case. the problem is, the argument that amazon is making, it is overbroad, it is invasive, it is a violation of privacy. at they are on a fishing expedition. if i'm making the on behalf of amazon, which i'm not, but if i was, i would say, the only time that the recording kicks on is when you say the week word, "alexa." so what leads prosecutors to believe that at any point, the alleged murderer said "alexa," and then said things may be like "how do you get rid of bloodstains?" "how do you dispose of bodies?"
