"This report provides a brief summary of the work carried out by the United States Attorneys' offices during the fiscal year. While this abstract of caseload statistics, program discussions, and case summaries does not fully impart the work of the United States Attorneys' offices, it provides a glimpse of the types of cases the offices are handling, the offices' commitment and dedication to prosecuting and litigating cases, and the diversity and complexity of the caseloads and work conducted around the country. [...] The United States Attorneys' offices conduct most of the criminal prosecutions and civil litigation handled by the Department of Justice. The offices investigate and prosecute a wide range of criminal activities, from organized drug trafficking and violent crimes, to environmental offenses, to health care frauds, to corruption bypublic officials. In the civil arena, the United States Attorneys' offices defend federal government agencies, for example, in tort suits brought by those who allege suffering as a result of government actions, or alleged medical malpractice by federal employees. The United States Attorneys also initiate civil cases against individuals or businesses to enforce the laws, such as in civil health care fraud cases, or to represent the government's interests, such as in bankruptcy actions."
