How to Build a Rapport With Criminals

A main plot device in mine hunter is like building up insincere rapport with criminals. In that show the fbi agents are talking to convicted criminals so i think there's a big difference when you talk about someone who has already been convicted at that point. I don't have a lot of problem with that but i do have much more of a problem when you're talking about someone who is presumed innocentsomeone who is just a suspect. It seems like it's rapport building and if the person was guilty maybe it would be which is also partly why i selected that episode because i feel like of all the episodes that is maybe the most ambiguous one.
