Yes I do not hold a degree in psychology, and you clearly have a superior education in that branch of science if you’re able to tell that I have none.
So please in your educated opinion explain to me why you think that it was illogical for a very educated man with no prior psychosis notes to wear a ballistic neck guard, ballistic vest, shin guards and a gas mask while going on a shooting spree and why it made much more sense for him to wear it “to look cool”.
My humble uneducated opinion suggests that it’s logical to wear armor when going into a shooting spree. :dunno
