Debate continues over creating taller, larger fences on the U.S. southern border. Meanwhile, the northern U.S. border utilizes no fence to maintain security. Some advocate that fences are crucial to U.S. border security. Others counter stating that fences are extremely costly and do not deter those from crossing illegally to such a degree to justify their price.
State whether you are for or against the development of more and larger fences on the southern U.S. border. Are the arguments for and against fences valid and reliable in terms of their supporting data and research?
