Knoll wrote an article about "pseudocommandos." He pretty much owns the term and he's going to trot it out whenever something happens that has the slightest resemblance to his theory.
There's probably going to be a lot of controversy between those who play up the autism/Asperger's theory and those who are looking for other explanations. In an earlier article, Knoll mentioned those who saw Asperger's symptoms in Jeffrey Dahmer, but here he's going out of his way to avoid discussion autism.
The impression I get is that the psychodynamic stuff may have some validity, but this shooter was very, very distant from the rest of humanity and from ordinary feelings.
The comments from a high school friend of Lanza’s are very revealing.
