Amaral messed the investigation up. It seems that people are sucked into things because they dislike the 'McCann's as you said the McCann's created this in the first place'. So you believe that Amaral should be awarded for the mess he caused? A little girl was missing and all he could think about was accusing the McCann's with no evidence, then when taken off the case, decided to write a book and poison the name of the McCann's for his own gain.
Kate's book on the other hand, showed the investigation through her eyes. How Amaral turned on them and was not looking for their child.
Jon Clark also points out everything that went wrong with the case.
The obsession with Amaral is alive and well I see. Lest we forget, he wasn't in charge of the investigation, Encarnacao and Neves were. According to Kate McCann it was those two who ignored the law too and accused her and her husband of being involved in their daughter's disappearance. They interviewed them with no lawyer present and there's no record of what was said.

I've always wondered why this departure from the accepted procedure wasn't reported by the McCanns and why they and their supporters have chosen to concentrate on Amaral, the third in the chain of command. His opinions were clearly shared by his superiors.
