There was a guy talking about how he got stopped by the police and got his trezor confiscated because they thought it was a voice recorder.
Voice recorder aren't illegal. Why would they confiscate something for looking like a voice recorder?
We don't even know if the story is actually true or someone just trolling reddit. However, it's not uncommon for police to want to have complete command over a situation and they typically don't like to be audio or video recorded. That said, they aren't known for having very much smarts. If the story is true the cop would have to be a moron to mistake a usb-like device for an audio recorded.
