The report that Lansa's had Asperger's may not be true like many other things that have made the news. I agree, it will be interesting to see more information about it. I know little about it except the one person I know who is about 30 now, intelligent, especially when he was younger, but physically clumsy and antisocial. He has never had anything to do with guns and has never been violent with anyone or anything.
All I know, is that it took an unusually cold blooded killer who was VERY proficient with a pistol. That takes many hours of practice. This person was able to carry this out alone, under great stress, in an unfamilar area. Doesn't sound to me like something a skinny, quiet, timid, shy autistic would be very good at. Maybe he isn't the same person as his picture indicates. The picture published was some years ago.
Maybe he was just a damned psycho as one FRiend pointed out on another thread. Even so, that level of skilled with a pistol required many hours of practice, IMO.
Intelligent and uncomfortable, loner left few footprints in life
