The far right has been promoting gun sales not for sport or safety, but also as a preparation for a revolution they want/expect to come.  I have talked to several very conservative friends over the last decade 'preparing' for a social upheaval of armed violence.   They believe it, they are preparing for it, they will act on their fears, real or not.

Clearly the far left is moving in the same direction and from looking at world history, we know both left and right have turned to violence for power and control.   

Hopefully this event will lead to overwhelming condemnation of violence as an alternative to a negotiated evolution of our nation in facing new conflicts and challenges in modern world.    It's my belief that the current bi-polar design of our political structure is failing and in serious need of reform.  

Violent revolution is not reform, but left unchecked violence certainly has power.
