George Zimmerman was acquitted of killing Trayvon Martin, a New Orleans attorney complained to me Monday, because the prosecution didn't want to win a conviction. The attorney, who has worked at Tulane and Broad as an assistant district attorney and as a defense lawyer, called me to say that he's handled hundreds of homicide cases over his career and that he's never seen prosecutors who want to win make the series of missteps that the Florida prosecutors made. So he's convinced they lost on purpose. He offered six reasons for his belief that the state threw the case.
