Attempting to stop the flow of illegal immigrants by militarily patrolling the border with vehicles and agents is not feasible. There are almost 2,000 miles of Mexican border (Strayhorn). To adequately patrol this area would require several agents per mile of border. It would necessitate increasing the size of the Border Patrol to as much as ten times its current level. Additional vehicles and weapons would also need to be procured. The cost of this arrangement would be unaffordable even in good economic times. With the current obligations and the mounting budget deficit, the additional manpower required for strict patrolling of the border is not a realistic option.
