Amazon Echo is a hands free speaker that is controlled by your voice.[1] Echo answers to the name Alexa, and plays music, reads audiobooks aloud, gives headlines, and does so much more.[2] But, is one of Alexa’s “skills” the ability to help solve a murder?

This question is being asked in connection with a murder investigation in Bentonville, Arkansas.[3] Police have issued a warrant asking Amazon to produce the transcripts, voice recordings, and other information that an Echo speaker may have recorded the night of the murder.[4] But, the chances of Alexa being helpful in solving the murder are slim. This is because Echo is not recording everything that you say in your home.[5] Instead, the Echo is listening for “hot words” like the word “Alexa.”[6] While the Echo’s microphone is always on,[7] only upon hearing the word “Alexa” does the device begin recording for the amount of time it would take to make a request, and then it sends that audio to Amazon.[8] These recordings are then stored “until the user deletes them through the Echo smartphone app or on Amazon’s website.”[9] The user knows when Echo is sending audio for Amazon to store because the ring on top of the Echo illuminates and turns blue.[10]

Even though there is only a slim chance that the Echo could help solve the murder, Amazon has refused to turn over the data to the prosecutor.[11] Amazon released a statement stating “Amazon will not release customer information without a valid and binding legal demand properly served on us. Amazon objects to overbroad or otherwise inappropriate demands as a matter of course.”[12]

The prosecutor’s request for the Echo data has brought the privacy implications of voice activated speakers and other smart technology to the forefront of legal discussions.[13] Even though police have historically taken other electronics such as computers and cell phones to help solve crimes, the question remains whether new devices with built in microphones that are theoretically always listening should be subjected to the same standard as computers and cell phones.[14] Rather, the question becomes “is there a difference in the reasonable expectation of privacy one should have when dealing with a device that is ‘always on’ in one’s own home?”[15]

The Fourth Amendment provides people the right “to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.”[16] In order to assert a claim under the Fourth Amendment, you must have a “reasonable expectation of privacy, which contains both an objective standpoint and a subjective standpoint.”[17] On one hand, the argument can be made that there is a reasonable expectation of privacy because even though one chooses to put this technology in their home, they are not necessarily consenting to having their private conversations broadcasted to the world. However, in Smith v. Maryland, the Supreme Court held that “a person has no legitimate expectation of privacy in information he voluntarily turns over to third parties.”[18] Therefore, since the Alexa requests are sent to Amazon (a third party), it may also be argued that one does not have a reasonable expectation of privacy when it comes to these recordings.

While it is unclear how the courts will deal with the privacy issues that smart devices with always on microphones like Alexa pose, there are avenues for purchasers of these devices to protect themselves. In addition to deleting the recordings in the Alexa app, users are also able to turn off the microphone on the device, by pushing “the microphone button on top of the Echo” and then waiting for the button and the ring to “illuminate bright red to let you know it is not listening.”[19] But, until the answer to the privacy level question for these devices has been determined by courts, turning off the microphone when not in use and deleting requests from the app is probably the safest avenue for purchasers of Alexa to protect their privacy.
