American protesters came to the streets across the country to express their anger over the acquittal of George Zimmerman, who killed an unarmed African - American teenager.The demonstrators took to the streets in Los Angeles, New York, Oakland, Chicago and several other cities on Saturday night and the early hours of Sunday.Angry people also burnt flags, smashed windows and police cars. Protesters held a banner declaring: " We Are All Trayvon Martin. "The rallies came after a six - woman jury in Florida said that Zimmerman’s fatal shooting ofTrayvon Martin was justified, acquitting him of second - degree murder and manslaughter.The controversial verdict was read on Saturday night after three weeks of testimony and 16 hours of deliberation, rejecting the prosecution’s contention that Zimmerman, a former neighborhood watch volunteer, had deliberately followed Martin for suspecting him as a criminal and shot him to death after a fight he started.Zimmerman said the fatal shooting, which took place on February 26,2012, in the small city of Sanford, was in self - defense." How could you kill somebody and get off? It ' s a stark felony, " one protester asked." He racially profiled Trayvon, he stalked him, and he murdered him, " another protester said.Protesters in Chicago shouted: “Who killed Trayvon Martin? The whole damn system? ”Meanwhile, Florida state attorney Angela Corey defended the decision to prosecute Zimmerman for second - degree murder." What we want is responsible use when someone feels that they have to use a gun to take a life. They have to be responsible in their use and we believe that this case all along was about boundaries and that George Zimmerman exceeded those boundaries, " Corey said.However, Zimmerman ' s defense team was critical that he was even brought before a court." I think the prosecution of George Zimmerman was disgraceful. I am gratified by the jury ' s verdict, as happy as I am for George Zimmerman, I ' m thrilled that this jury kept this tragedy from becoming a travesty, " Zimmerman ' s Defense Attorney Donald West said.
