Seems quite different from this case. The agent you're referring to stated his intentions up front quite clearly. As far as I can tell the only details revealed by the FBI in this case is that they had some "documents" (without giving any context) for the author to review and answer questions about, and refused to share any details with her lawyer. I'm not discounting that there are FBI agents who behave properly and politely without pushing the limits of legality, but I also believe there's plenty of evidence to suggest that there are plenty of agents who share none of those qualities (note that I'm not speculating on what fraction of agents are in each bucket, just that both are non-zero).
