A clumsy 20 year old autistic kid dressed in camo and full body armor who never shot a gun before, drives to another state , gets let into a locked school looking like rambo, and kills 26 people with dead on accuracy at a school his mother, a retired teacher (who no one ever heard of before), used to work in years before, after allegedly shooting her, whom the guns belonged to in the first place, and then takes his own life? Yeah I'll believe that.
