Leon Kiklinski is a member of The Blacklist.
Leon Jeremy Kiklinski was raised by his parents until he watched his father being beaten to death by police officers in his father's liquor store when he was 12. Despite Leon testifying at trial, the police were acquitted after they edited the surveillance tapes to make it look like Leon's father was resisting arrest and released it to the public. After this he became a terrorist-for-hire who specialized in media manipulation. He was hired by “The Gambler” to frame the FBI for the “assassination” of Ryan Dupont, an activist that spoke out against the police and law enforcement brutality.
