Introduction The Secret Service is an agency within the Department of Homeland Security. Its main mandate involves handling issues of counterfeiting and other financial crimes that are committed in the USA. As Emmett reveals, following the killing of William McKinley, the agency’s mandate expanded to include protecting national leaders, dignitaries visiting the US, and the leaders’ families. Towards the end of the national battle in the US, about 33% and 50% of the money that was being exchanged was forged. This situation led to the establishment of the Secret Service agency in 1865 to deal with crime, which posed an enormous threat to the US economy. This paper discusses the history and development process of the United States Secret Service agency. It also discusses the mission, structure, funding, policies, success, and obstacles to the performance of the organization. The goal is to offer a comprehensive analysis of the organization’s extent of attaining its objectives that were defined during its creation. In the last section, an analytic conclusion of the United States Secret Service is offered. History and Development of the United States Secret Service The Secret Service (SS) was inaugurated on 5 July 1865. Instances of insecurity were very common because bandits had taken advantage of the situation where no proper safety mechanisms had been established to detect any evil plans before they could be executed. Hence, its main mandate was to curb the increasing cases of counterfeiting the US currency. The agency was commissioned as a division of the treasury section. It was established through Abraham Lincoln’s ruling, just during the time of his murder. Before its commissioning, the United States Park Police, United States Postal Service, the US Marshals Service, and the US Police Office Department served as the only bodies that were mandated with enforcing federal laws. Marshals’ Service lacked the capacity to investigate crimes that were committed within federal jurisdictions. Thus, in 1867, Secret Service started investigating all crimes ranging from murder and illegal gambling to different forms of theft such as personality robbery, information systems theft, or cyberspace theft. Although the agency was commissioned in Washington, DC, its main offices were moved to New York City in 1870. However, they were later returned to Washington, DC in 1874. In the mid-1870s, the agency gave out a fresh set of devotion manuscripts to the senior management. At the close of the 1870s, the US Upper House made it illegitimate to forge money or any other highly valued metals. The agency was tasked to enforce the law. According to Kessler, the agency was recognized as a separate entity within the banking section of the United States of America in 1883. The bureau first offered the head of states defense as a non-official duty requirement in the mid-1890s.To formalize the mandates of the agency; the US Upper House enacted and passed a law on forgery and/or purchasing of any fake stamp. Following the murder of President McKinley, the Upper House unofficially demanded the SS to temporarily guard the leaders of the United States. However, this role was formalized
