Guardian Angels founder and NY1 personality Curtis Sliwa claims that Junior Gotti threatened to kill him while the two were in Manhattan federal court yesterday. Right as Gotti's pre-trial hearing for racketeering conspiracy was breaking, Sliwa claims Gotti turned to the radio host who was in attendance and said, "You're going down." Sliwa shot back, "F*ck you!" But Gotti's lawyer told reporters that his client was saying, "He's going down" to a nearby friend that he was meeting downstairs. Capice? Sliwa may have been a little on edge (even for him) as he mentioned that Friday is the anniversary of the 1992 incident where he was shot twice and kidnapped, only to escape out of a speeding cab. He thinks it was set up by Gotti due to Sliwa's AM onslaughts against the Gambino crime family. Gotti might really be smirking widely now since a judge told prosecutors they need to present some new evidence to dispute Gotti's claim that he gave up a life of crime in 1999.
