My wife was watching NCIS the other day. The scene was in their forensics lab. There was an Amazon Alexa device there and in use. I know US TV in particular likes the money from product placement, and I have no doubt Amazon paid a pretty penny for that, but it totally killed any pretence at realism for me. I can't imagine a federal investigative agency allowing something like that on their internal networks, let alone somewhere where sensitive conversations are being had.
