last of which occurred within ten years (excluding any period of imprisonment) after the commission of a prior act of racketeering activity. The US Supreme Court has instructed federal courts to follow the continuity-plus-relationship test in order to determine whether the facts of a specific case give rise to an established pattern. The illegal acts comprising a pattern are called "predicate" offenses. Predicate acts are related if they "have the same or similar purposes, results, participants, victims, or methods of commission, or otherwise are interrelated by distinguishing characteristics and are not isolated events." Continuity is both a closed and open ended concept, referring to either a closed period of conduct, or to past conduct that by its nature projects into the future with a threat of repetition. Application of RICO laws Although some of the RICO predicate acts are extortion and blackmail, one of the most successful applications of the RICO laws has been the ability to indict and or sanction individuals for their behavior and actions committed against witnesses and victims in alleged retaliation or retribution for cooperating with federal law enforcement or intelligence agencies. Violations of the RICO laws can be alleged in civil lawsuit cases or for criminal charges. In these instances, charges can be brought against individuals or corporations in retaliation for said individuals or corporations working with law enforcement. Further, charges can also be brought against individuals or corporations who have sued or filed criminal charges against a defendant. Anti-SLAPP (strategic lawsuit against public participation) laws can be applied in an attempt to curb alleged abuses of the legal system by individuals or corporations who use the courts as a weapon to retaliate against whistle blowers or victims or to silence another's speech. RICO could be alleged if it can be shown that lawyers or their clients conspired and collaborated to concoct fictitious legal complaints solely in retribution and retaliation for themselves having been brought before the courts. Although the RICO laws may cover drug trafficking crimes in addition to other more traditional RICO predicate acts such as extortion, blackmail, and racketeering, large-scale and organized drug networks are now commonly prosecuted under the Continuing Criminal Enterprise Statute, also known as the "Kingpin Statute". The CCE laws target only traffickers who are responsible for long-term and elaborate conspiracies, whereas the RICO law covers a variety of organized criminal behaviors.
