Post-Trial Civil Unrest?

About 11 a.m., MSNBC reported, perhaps first, that two local police departments had asked the judge in the Zimmerman case to hold off announcing any jury verdict if it comes on a weekend, fearing civil unrest.  Not sure these days how much the timing would matter, but still revealing.  Since that report, MSNBC has gone out of its way to cool matters, why asking guests to comment on whether justice served in any case since the Martin family got its day in court.  Indeed, one guest, I believe Jonathan Capehart of Wash Post, claims that Trayon's mom told him months ago that she would accept any jury verdict.

Indeed, local police have already released a PSA video appealing for calm as the jury considers the case. Watch it and an earlier one here. 

The 36-second video features law enforcement officials, kids from the Jason Taylor Foundation and James Jones of the Miami Heat. The participants shout "raise your voice, not your hands" and "let's give violence a rest, because we can easily end up arrested." Broward County Sheriff Scott Israel said in a statement on the website that his agency has no information "about a specific event that might take place at the conclusion of the trial, but we encourage everyone to keep any protests peaceful."

Interview with local police chief here.  Seems like preparations launched when it became clear to many that the prosecution was fumbling the case.
