The Amazon Echo's always-listening feature entangles it in a murder case

Police in Bentonville, Arkansas would love to know whether an Amazon Echo picked up the sounds of a crime. As reported in the Washington Post, the investigation highlights the privacy issues around increasingly popular smart-home products. The Amazon Echo in question was present in a home where a murder took place in November. Victor Collins was found dead in a hot tub after a social event that went late into the previous night. Police found the Echo among many other smart devices in the home, but the Echo is the only one that records what you say.
