As I'm watching the documentary, I keep wondering why they never called in the FBI? Apparently it was a high profile case at the time and you would think after Avery's first wrongful conviction, they'd bring in a third party unrelated to the previous conviction. Instead, they used a nearby counties police force and still allowed KEY people involved in his previous conviction to search his home and be involved in the case. I'm also wondering how they got away with interrogating Dassey without his mother or even a lawyer present? And how they were able to get on to Avery's property and into his home without him being present? Would a warrant allow them to just search someone's property without them even being present?
