Patsy and John won't be eliminated in the mindset of the police, because they were in the house---that's seems to be SOP for the cops. There has been limited face to face contact in all these years between the Ramseys and the police, for reasons we're well aware of. It looks to me like they were following up on all the unanswered questions---perhaps trying to verify previous answers where Patsy couldn't remember the events. It's obvious Kane and Wood don't like each other---two lawyers---two egos. With the bickering back and forth, the questions got lost...the train of thought. I blame them both equally......it could have gone smoother.
