Mafia informant
An organised crime insider who testifies against associates for a reduced sentence
A mafia informant is a person connected to organised crime who chooses to cooperate with the police or the prosecution by giving testimony against former criminal associates, often as part of an agreement on sentence reduction or complete immunity from prosecution. The term is used primarily in coverage of American organised crime and corresponds most closely in Danish to the concept of a kronvidne — a charged or convicted person who testifies against others in the hope of a procedural advantage.
The classic example is Salvatore 'Sammy the Bull' Gravano, who in 1991 entered into cooperation with the FBI and gave testimony against Gambino family boss John Gotti. Gravano pleaded guilty to, among other things, complicity in numerous killings, but received a markedly reduced sentence in return for his testimony, which was decisive for Gotti's conviction in 1992.
In American law the institution is formalised and widespread, not least through the federal RICO framework, which gives prosecutors strong incentives to enter into cooperation agreements with insiders from organised criminal groups. A mafia informant may thereby obtain witness protection, a new identity and a drastically reduced sentence.
In Danish usage, 'mafia informant' is not an independent legal institution and does not appear in Danish legislation as a defined concept. It is used descriptively about a type of cooperating witness and is not subject to separate regulation in Danish criminal law. In Krimidex the term appears exclusively in the context of foreign — primarily American — organised crime.
