Be careful what you say around your Amazon Echo, you never know when it will be used against you in court. Amazon says that it will not release any information to the authorities "without a valid and binding legal demand" but that doesn't mean prosecutors wont be back with a warrant. Amazon declined to give police any of the information that the Echo logged on its servers, but it did hand over Bates' account details and purchases. Police say they were able to pull data off of the speaker, but it's unclear what info they were able to access. Due to the so-called always on nature of the connected device, the authorities are after any audio the speaker may have picked up that night. Sure, the Echo is activated by certain words, but it's not uncommon for the IoT gadget to be alerted to listen by accident.
