Just as a sidenote: even if he had a history of mental health issues resulting in violence, staging and planning an attack like this basically disproves most variations on mental health defenses
He had enough presence of mind to have possibly staged a dry run:
Investigators are exploring whether Las Vegas suspected shooter Stephen Paddock sought a hotel room overlooking another outdoor concert in Las Vegas in late September that featured Chance the Rapper and Lorde, two sources told ABC News.
Paddock allegedly rented multiple condos at The Ogden complex in downtown Las Vegas, which overlooked the location of the Life is Beautiful Festival.
Everyone wants to believe someone would have to be insane to commit an act of violence, but that’s not true. Someone can be perfectly sane and come to the conclusion they want to kill people.
That’s why framing the gun control debate around mental health regulations is and will always be BS.
