20 POLICE JULY 2018 Some homes and offices have more than one of these Amazon or Google devices. (e author has three.) ese devices listen for their wake words and execute spoken commands such as tell- ing time, setting alarms, playing online radio stations, and answering simple questions. With additional accessories, they can also manipulate thermostats, lighting, and other controls. Smart speakers are showing up at more and more crime scenes. During a presentation at last month's Techno Se- curity & Digital Forensics Conference four out of approximately 50 digital forensics analysts attending a presentation on IoT de- vices said they had dealt with smart speakers. e presence of such devices at crime scenes means officers and analysts need to know how to handle them. e most im- portant thing to know is what not to do. Don't say the wake word. If you do and the system hears it, you will destroy evidence. e system has very limited onboard memory. Saying the wake word erases one of its most recent commands. Most of the data from smart speakers, however, is captured in the app on the owner's phone or tablet or on the cloud. ese devices are not computers; they are portals to computers in the WHETHER YOU'RE DEFENDING FREEDOM OR ENJOYING IT, OUR OPTICS ARE READY FOR ANYTHING.

If you really need the command data from a smart speaker your best bet is to access it from the app on the owner's phone or tablet. And of course, the easiest way to do this is to get the victim, suspect, or other individual with legal standing to give you the user name and password. at's exactly what happened in the most publicized instance of investigators seeking evidence from a smart speaker. Benton County, AR, prosecutors served Amazon with a warrant for the cloud data from a murder suspect's Alexa. Amazon fought the warrant, as it probably didn't want to set a precedent of handing over such data. After months of legal wrangling, no precedent was set. e suspect's attorney gave the prosecution the user name and password for the app. DON'T SAY THE WAKE WORD TO A SMART SPEAKER AT A CRIME SCENE.
