Absolutely spot on. These are the “great unknown” nobodies who think that their firearms slaughtering people will win them fame.
As in the old West, more often than not, these punks got it, and early on. Simply psychopaths.
The backgrounder on the mom protecting the punk whacko in the extreme (about neighborhood noise, etc. bothering his sleep). This washout from boot camp, trods around like a wannabe. It fits many many profiles.
So, the answer is NOT gun free zones to entertain these fantasies of greatness and importance, the product of a narcissistic society (and prez). It is an armed populace, in proximity on campus with security and/or concealed carry.
This washout from boot camp,....I have heard this numerous times. Why did he wash out? Peed his pants at night? Physically unfit (didn’t look like it)? Attitude (mentally incapacitated)? Inquiring minds would like to know.
