The Tampa chief of police was subsequently indicted as an accessory after the fact for covering up the department's involvement. Amazingly, several of the policemen were convicted, leading the American Civil Liberties Union to declare that it was "a victory for civil rights in Florida and the beginning of a new drive against the Ku Klux Klan." But the verdict was overturned by the Florida Supreme Court, which ordered a new trial. During the retrial, the judge's actions were so suspect that the prosecutor requested that he be removed. The policemen were subsequently found not guilty.
This book chapter covers the story in some detail.
