This country can ban firearms, cars, knives, alcohol etc. Uh, the 21st Amendment didn't work too well. Why aren't we focusing on the root cause of the problem, people. Especially people who are afflicted with mental illness. Back in the day it was mostly Postal Workers that went postal. Now its just any disillusioned stooge that wants to kill large amounts of people. Why? Some of these mass killers have been captured alive. Why not conduct extensive psychological tests? Including brain tissue examination. I'm a believer of the Samer Theory. There might be a definitive cause making people go fúcking nuts. Whether it's road rage, political agendas or mass killings; we as Americans are losing our collective minds.
