Should the American government focus the bulk of its law enforcement resources on fighting organized crime, or counter-terrorism?

Research and develop and addresses the following:

Discuss the history of organized crime in America. Include in your discussion a definition of organized crime; a detailed, thorough example of a criminal organization currently operating in the United States; the types of crimes it engages in; and (if possible) who its leadership is. Include a discussion of rival criminal organizations.
Discuss the history of terrorism in America, and make sure to include domestic terrorism in your history (do not forget that prior to 9/11, the most devastating terrorist attack on U.S. territory was perpetrated by a fellow American). Detail the various terrorist activities and the organizations behind them that have taken place on U.S. soil.

Transnational Organized Crime: What the FBI investigates.

The FBI is dedicated to eliminating transnational organized crime groups that pose the greatest threat to the national and economic security of the United States. The Bureau has found that even if key individuals in an organization are removed, the depth and financial strength of the organization often allow it to continue, so the FBI targets entire organizations responsible for a variety of criminal activities. The Bureau draws upon the experience, training, and proficiency of its agents; its partnerships within the intelligence and law enforcement communities; and its worldwide presence, using sustained, coordinated investigations and the criminal and civil provisions of the Racketeer Influenced and Corrupt Organizations Act (RICO).
