George Zimmerman

A few months after the jury announced George Zimmerman was not guilty in the Florida shooting death of Trayvon Martin, NBC News legal analyst Lisa Bloom published a book examining the case, “Suspicion Nation: The Inside Story of the Trayvon Martin Injustice and Why We Continue to Repeat It.”

In “Suspicion Nation,” Bloom looks at what happened behind the scenes and why similar shootings continue to take place, including the August death of Michael Brown in Ferguson.

A mixture of sadness, resolve and, at times, anger permeated through a non-violent crowd that spilled from the steps in front of the St. Louis Justice Center into Tucker Ave. in front of City Hall.

The mood at the rally held in downtown St. Louis on Sunday night echoed through similar events in cities and towns across America, as people gathered to voice their disappointment over the acquittal of George Zimmerman for all charges in the shooting death of Florida teen Trayvon Martin.
