Surely though the point is how many people are charged with lying to an undercover agent?   Legally how can anyone be charged with lying to the fbi if they aren’t informed that any statement they make is being entered into record... it’s completely different legally if you use an undercover agent to obtain intelligence that will lead to gaining evidence...  Though the whole argument is moot... the FBI have admitted Flynn didn’t lie and those FBI agents who duped Flynn had to change their 302s to try to say he did lie... (they just didn’t think they would be found out at the time)now that’s illegal! So what do FBI agents get for lying to the FBI?
