The tax evasion takedown...According to Wiki, John Gotti (John Joseph Gotti Jr.) was an American gangster and boss of the Gambino crime family.
"At his peak, Gotti was one of the most powerful and dangerous crime bosses in the United States. During his era, he became widely known for his outspoken personality and flamboyant style, which gained him favor with some of the general public. While his peers generally avoided attracting attention, especially from the media, Gotti became known as "The Dapper Don", for his expensive clothes and personality in front of news cameras. He was later given the nickname "The Teflon Don" after three high-profile trials in the 1980s resulted in his acquittal, though it was later revealed that the trials had been tainted by jury tampering, juror misconduct and witness intimidation. Law enforcement authorities continued gathering evidence against Gotti, who reportedly earned between $5 million-20 million per year as Gambino boss."
In 1992, Gotti was charged with: Racketeering; racketeering conspiracy; murder; Illegal gambling; obstruction of justice; and conspiracies to murder, bribe a detective, obstruct justice, commit loan sharking, and commit tax fraud. The verdict was guilty. His sentence was, life imprisonment without parole and $250,000 fine.
