You are the paralegal in the organized crime practice in a large law firm. In the face of a looming budget deficit and likely cutbacks ahead, your lead attorney has asked you to write a memorandum justifying the future existence of the RICO (Racketeer Influenced and Corrupt Organization) criminal defense practice. You should demonstrate your understanding of organized crime and present a detailed argument to support maintaining a criminal defense practice. Be sure to explain and discuss the RICO Act, including the nature of what this act covers, what types of incidences are involved in organized crime, and what prosecutions have happened under the RICO Act.
