I don't believe that I have ever seen a picture of a mass shooter at his prom. Who were they supposed to share their feelings with? Ramos, whose nickname at the Wendy's where he worked was "school shooter", apparently did this to impress a 15 year old German girl he met on social media. Even low intellect men with bad social skills have a sex drive. What does an 18 year old guy think about more than girls? What the shooters all had in common is a repressed sex drive, with all likelihood that they will never touch a real woman, and no one to talk to about it, because it is unacceptable to talk about it.
