Is The Zimmerman Case Evidence Of Modern Racism?

I do not believe that the aquital of George Zimmerman is the result of Modern Racism. Liberal America insisted on the immediate arrest and formal charging of Zimmerman rather than a thorough investigation that may have revealed that there was not enough evidence to proceed with a murder trial. As for the allegation that modern racism against minorities played a roll in the verdict, the reality is that the jury had no other choice but to aquit.e
Does the name O.J. Simpson come to mind? Was his aquital a case of modern racism against white victims?
