All true!
I would still remind people about the General Flynn scenario talking with FBI agent Peter Strzock without a lawyer present.
Don’t even talk to the FBI with a lawyer present. Even with a lawyer present, record the conversation.
Have read stories of the FBI showing up the office of someone’s lawyer and FBI agents being told that they were going to record the meeting. FBI tells the lawyer that they are not allowed to have their interviews recorded. Lawyer tells the FBI he is going to record the interview anyway. FBI agents get up and leave the meeting. Apparently the FBI wasn’t all that interested in the interview if it was going to be recorded.
