What profile from Sutter would make you believe that he would snatch a little boy? I'm not defending this low life by any means, IMO there are so many levels of crimes and one does not equal the other. Women get raped & killed but that doesn't mean that every rapist is a killer. Children (sadly) get abused sexually all the time, but the family pedo may never ever touch the neighbor down the street and vice versa. IMO pictures of child porn is sick enough, but thatat doesn't mean that this guy goes out and kidnaps strangers or kids in the area. He could look at pictures for his own gratification/satisfaction, he could look at pictures and get gratification/satisfaction somewhere else with an adult, he could look at pictures and abuse family members, his own children, his nieces/nephews/cousins etc. It's also vice versa, a person could snatch a child and do horrific things all the while never once looking at a child porn photo.
IMO - one does not equal the other. This guy IMO is disgusting and I would think that LE is carefully looking at many previous investigations and cases that he may have touched just to make certain that no cases have been compromised based on the knowledge that they now have. I just can't see this being linked to Dylan other than the location.
