My two cents on the Trayvon frenzy: there’s a big element of emotional displacement of black anger with the President transferred to this case. Many blacks are deeply disappointed with the Obama Presidency, in particular the terrible unemployment because of his destructive handling of the economy. Life for millions of black citizens has gotten worse, not better, under the African-American President, but it is taboo to criticize him, so their outrage has been funneled into the highly publicized shooting and trial.
If there were jobs and a sense of hope about the future, the trial’s outcome might have been more easily accepted. But Obama has given far more attention to the imagined concerns of hispanics than to his own paternal race, who have to riot to get noticed by the President.
