I have not recorded anything. I use cheat sheets and take hand-written notes as close to the action as possible. This is very useful but not infallible.
I understand that even the hardiest human memory can falter and that accuracy may suffer. I understand the intent to use the recordings only for the noble purpose of accuracy in reporting and research. I understand the need for accuracy in reporting and research.
As I consider the ideas here, I am trying to imagine a trial..... Shopper # ############ (no names, please) is being cross-examined about a personally obtained recording made of the exact statement made by the defendant during the opening remark of the interaction in question.
"Are you saying, shopper # ############, whose name is secret, that you acted in the spirit of the law when you secretly taped the defendant (male, 8'3", bald, no glasses, muscular, known to hang out near fume-y household cleansers), when he was doing his job and following orders to say, "Good morning!" to you and all other customers?
"Yes. You see, I was following orders to quote what the defendant said to me at the beginning of our interaction. If I just say what he said without proof of it, I am gossiping and giving hearsay testimony, which is considered inferior."
Now, our defendant is just Mr. Clean. He is a non-issue... unless you think he has an issue with fumes.
But who would want to deal with a legitimate legal challenge?
