What does IQ have to do with ability to shoot? could just be a savant, stranger things have happened. Imagine being an autistic savant and the only thing your good at is shooting, but your the best at it. nobody wants to be your friend because your a creepy autist, so you do what you do best. Reading his story on wikipedia, the guy was clearly tarded, a loner and just all around in a bad place. Cant say one way or another. Might have been framed, i think tarrant was a false flag and similar laws were pushed in the aftermath of that. I know kikes do things like that.
