I read the letter. It was put up on social media. Other people saw it as well but I don't think they'd do anything about it. I'm concerned for the lawyer. The letter does not make him look good at all. I don't know if the lawyer already knows about it and I think he should be told about it just in case. I don't personally know the people involved. I just assume most lawyers would want to know if their name, firm address, email address were being used to send a letter with empty threats, or any threats.
