However, I would relate the causes and/or indicators you refer to a little differently. I believe strongly that Zimmerman's is a political prosecution, and standing alone, that is a horrible thing to happen in a supposedly "free" country. But I don't see that as an indicator of a coming national crisis, but rather as a symptom of the crisis that this country is in the ending stages of, not on the cusp of. In the bigger scheme of things, the Zimmerman/Martin case is fairly insignificant. It simply came at a convenient time for opportunistic progressives, leftists, anarchists and Marxists to use it to foment chaos, so yeah, it may be what some of the more incapable-of-thinking-for-themselves, lemming-like rioters view as their "inspiration" to engage in the chaos. But to the pushers of the dishonest memes of racism, guns-are-dangerous-and-a-blight-on-our-otherwise-peaceful-and-safe-society, if it wasn't Zimmerman/Martin, it would be some other manufactured "outrage" that they'd use to rally people to violence. Lovers of big, all-encompassing government need chaos in the streets to overcome the obstacles to big, all-encompassing government that the Constitution puts in front of them. When law-abiding citizens can't feel safe in their own homes and communities, they will not only accept big-government intervention, but if the chaos is severe enough and sustained for long enough periods of time, they will demand it, thus voluntarily relinquishing more of their own freedoms for a sense of security, false though it may be.
Please don't get me wrong, festus. I'm not disparaging your well-reasoned and well-stated post. We don't disagree here at all. I just think we're well past being on the cusp of anything. Most all of us can envision widespread violence being triggered by this manufactured national controversy, which says to me that the groundwork for the breakdown of a moral and law-abiding society was laid many years, even several decades, before anyone ever heard the name of Trayvon Martin.
