What we do know for sure about the night of February 26, 2012, is that George Zimmerman shot Trayvon Martin to death in Sanford, Florida, later claiming self-defense. Despite altogether too many having made up their minds about who was to blame within minutes of hearing of the incident, and the biased, tainted press reports, enough facts have subsequently shaken out that I believe a reliable determination can now be made as to why Martin died that night.
