The United States Border Patrol has been in existence since 1904 and enforces and regulates laws under the Immigration and Nationality Act. The U.S. Border Patrol now falls under the Department of Homeland Security, created in response to the attacks of September 11, 2001. Over the years, their jurisdiction and missions have changed to better protect the nation's security. Although border surveillance is a necessity for any nation, one can often benefit from its extensive adherence to constitutional laws. The mission of the U.S. Border Patrol should be to prevent illegal aliens, who pose a threat to American society, from achieving their goal. Often their goals can be confused or executed in a biased manner. It is important to examine the history of Border Patrol before passing judgment. The Border Patrol has been around since the early 1900s. Their motto of professionalism, honor and integrity for human life has motivated them throughout the years. It began when guards on horseback were put in place to prevent the entry of illegal immigrants, on behalf of the U.S. Immigration Service. Over several decades, they have gained in funds, in strategy, in coordination and above all in organization. After the 18th Amendment banned the import and export of alcohol, the guardians had more ambitious goals and expectations. Many limitations were also imposed by the Immigration Acts of 1921 and 1924. The first Border Patrol Academy opened in 1934. In 1940, the Immigration Service became part of the Department of Justice . Later, Border Patrol agents were granted authorization to search illegal immigrants anywhere in the United States. This was very important because it made immigrants subject to arrest for the first time in history. But they could only be... middle of paper... The hard work of their work should not be overlooked, because for such a small group of people, they cover a lot of ground. Border Patrol will continue to evolve as different concerns arise around the world. It's part of being in such a culturally diverse nation that we deal with these kinds of issues more than others. As the world changes, our values ​​must remain the same.
