The evidence indicated that George Zimmerman was attacked by Trayvon Martin and he shot in self-defense. Letter writer Frankie Seaberry's theory is Martin was knocked to the ground, screamed for help, and Zimmerman shot him at that point? I guess we are to ignore all the forensic and eyewitness testimony? Even the testimony from prosecution witnesses was more favorable to the defense.
If I were to speculate, the more likely scenario was that Martin thought he was going to get the best of this white "cracker" but he failed. He had plenty of time to get to his dad's home. If he was so fearful, why didn't he call 911? Given what we know about Martin's previous behavior, he didn't seem the fearful type.
Florida authorities had it right the first time in not bringing it to trial yet the state appointed a special prosecutor to charge Zimmerman and we all know why. They got the trial, just not the verdict they wanted.
As for the Stand Your Ground Law: According to news sources and Florida statistics "Black Florida citizens have made about one-third of the state's total 'Stand Your Ground' claims in homicide cases, a rate nearly double the black percentage of Florida's population. The majority of those claims have been successful, a success rate that exceeds that for Florida whites." And in the Zimmerman case, the Stand Your Ground Law was not even invoked. The jury got it right.
