"A report by the Connecticut child advocate in 2014 concluded Lanza’s autism spectrum disorder and other psychiatric problems didn’t cause or lead directly to the massacre." 

This dimbulb gets paid (a lot) to consult on children's welfare. Ummmm, no, actually Lanza's psychiatric problems were a direct cause of his behavior. His autism dissociated him from the normal sense of right and wrong, and empathy that would have prevented him from slaughtering helpless children. The violent video games he played constantly reinforced that dissociation. 

I don't know why the FBI felt the need to throw in the pedophile comments of a woman who never met Lanza in person. Or why the AP felt the need to write this article. Lanza's actions were the behavior of a disturbed man with organic brain disorder, fueled by exposure to violent stimuli and left unchecked by an incompetent mental health system and narcissistic parents.
