Have you ever experienced mob psychology firsthand? I have. That's how I know that people who are part of mobs can and often do commit crimes they'd never do otherwise.

And when it comes to slavery, Jim Crow, and the lynchings, I believe that mob psychology - entrenched by society and government across many generations - is what led not only to the horrors Blacks have faced for centuries, but all the other tragedies faced by minorities e.g. every genocide up to and including the Holocaust.
