Probably a better method is to take a human witness with you, preferably a lawyer of judge, at minimum a video and audio recorder. One last thought, every, every single one, put in prison on Forensics Files swears they are innocent for the rest of their lives. Neither LVJustice nor I know if bosses were in that room or if they were 'just' peers or friends. If my peers and / or friends at work did something on either end of the Bell Shaped Curve then complained at the reaction we considered it a duty to harass them about it for months, and I'm a retired AT&T middle manager. In fact, I would already have had a keystroke app installed on your work computer automatically forwarding your input to HR and Legal.
