Professionals!? You mean the guys who refuse to record interviews with suspects? Now what reason could they possibly have for refusing to record an interview...

That makes them sound even more professional, if you consider it in their professional interest to cover their tracks.

Certainly problematic, but I wouldn't describe the problem with that as a lack of professionalism per se.

They aren't honest, they aren't trustworthy, they don't act in your interest... but they aren't juveniles either. They don't act like a bunch of out of control children on power-trips.
