I've read every Douglas book. He's a genius but when it comes to the Ramsey case.....he didn't know his



from his elbow.
IMO he was brought in early by Team Ramsey to taint him so he couldn't be a factor further down the road if he was ever brought in by BPD, FBI,etc. to help advise them on the case. Once Douglas claimed it was an intruder, Ramseys had no more use for him. Douglas claimed IDI without even getting to look at any of the evidence. One interesting thing about his profile of the killer is that half of it would fit someone in the house.....especially Patsy.
I always thought there are at least two people on earth who could've solved this case if they were handed all the files and could've interviewed the Ramseys.....Douglas and Ressler. Ressler is dead and Douglas ruined his reputation to an extent by defending the Ramseys when he didn't know all the facts.
