I don't believe you do. But I fear that there will be plenty of opportunities to come that you eventually will. This is a harbinger of things to come. I don't mean to talk you down. But I believe you don't understand the gravity of the situation. We will see. Hopefully I'm wrong.
I think there's reason for concern whenever people form groups armed with automatic weapons, but I agree with @bjorn that this 'Black Panther' paramilitary group looks like more serious business than the groups of 'rednecks' that we've seen marching with their guns – at least so far. I'm basing that on the fact that the BP have decided to wear 'military uniforms', masks, march in a formation, and that their supposed leader said that "They are going to take Texas."
Having said that, I remind myself that often these video clips are taken out of context, and there's always room for doubt of what's really going on. Let's wait and see...
