In 2015 U.S. Presidential applicant Donald Trump issued a proposition to build a barrier along the Mexico-U.S. border. The barrier would stretch out along the 1,900 mile outskirt and would keep illicit drugs and individuals from entering the U.S. In 2013 the Government Accountability Office revealed that the border patrol had caught 61% of people who had tried to cross the border that year. Experts state that building a barrier along the whole border is inconceivable since it parts of it contain rough, uneven landscape. Defenders contend that the barrier will eliminate the stream of illegal migrants and drugs into the U.S.
