Who except you would know that you have any recordings? They are just used to help you remember. Remembering exactly what was said.

You might have had your reasoning warped by lawyerings in this case.

if you make a recording, transcribe it, the delete the recording, it's probably hard to prove you made a recording. better yet with todays technology you can probably make a transcription live. i don't know if feeding he audio into a transcription tool counts as recording.

but the example was to use a recording in court. if you do that then everyone knows.
