Protests by race?
I don't think the protests carried on for the OJ Simpson trial, Michael Jackson trials, Rodney King trial, Watts Riot, Million Man Washington protest and the list goes on were all involving "racial killings."
Perhaps your question should be restructured, however, the Trayvon Martin case is an incredible tragedy. That a "protector of the community," Zimmerman, would shoot and kill a seventeen-year-old living in the community while making a Skittle run to the community store is ludicrous...and while on the phone make a racial slur indicating his own bias? Shameful.
It is an indication of the fears that continue to run rampant through American society. When a man who is himself protecting a community, shouldn't it be his duty to know who lives in the community? And should he even care about the color of skin?
Until the majority of American society quits with this slanted prejudice...these kind of killings will continue. Zimmerman himself looks Hispanic...so is this a minority on minority killing...or simply a sad little man who was looking to play hero in an age of fear?
The protests were needed to get action. The police chief has resigned, the court is still open in popular media, but the outcome remains the same. A boy was shot for no good reason--the shooter needs to pay a price for his foolishness. He was told to let the police take care of it. Why didn't he stop pursuit? He disobeyed his orders from an authority.
I feel and mourn with the Martins family...they lost a son...from friendly fire from a member of their community. Race has nothing to do with this...justice does.
