The mafia boss known as the "Teflon Don" was John Gotti. He earned this nickname because during the 1980s, he was acquitted in three high-profile trials despite serious charges, as the cases against him were undermined by jury tampering, witness intimidation, and other misconduct, making the charges not "stick" to him like Teflon
. Gotti was the head of the Gambino crime family in New York City and was also known as the "Dapper Don" for his expensive clothes and media presence
. His ability to evade conviction ended in 1992 when he was found guilty of multiple crimes including murder and racketeering, leading to a life sentence
