Sure, but all you'd get are commands you give Alexa ("Alexa, turn off the lights", "Alexa, what's the weather today"), which I suppose could be interesting to law enforcement, but certainly not as interesting as the "full-take" of an always-on wiretap.
I'm suggesting in order for the FBI to use Echo (or any other internet connected device that has a microphone) as a wiretap, the FBI could try to compel the manufacturer to write, sign, and push an update that causes the device to transmit audio to the FBI at any point.
That would have seemed a little far fetched in the past, but the current FBI/Apple situation could set a precedent.
