Here's an interesting theory. This part here is fact: His friend was a black guy. He told his friend he wanted to do a school shooting like at a college. His friend took his gun from him. After a while he gave the gun back.

Now this part I'm making up. Theory time... So why would a racist who hates black people have black friends? Perhaps he wasn't racist at all. Maybe he did want to start a war but a war on what? A war against the southern rednecks who like the confederate flag. They've been wanting that flag down for a long time. This gives them a good reason to. So the theory is he was a troubled democrat liberal on the far left and went Weather Underground ala Bill Ayers on those people. This is a known way of doing things where people pretend to be something they are not to instigate a war or violent situation so the other side looks like the aggressor.
