Now tell me, which one would be better trained to face this situation? Have you considered that smugglers could easily smuggle terrorists across the border with jars of biological toxins. The present system isn't working.
Those cultural and political reasons are just too important to set aside for the safety of our country. Before we put the military or any specially trained group in to protect our borders we need a solid committment from the administration and Congress to defend our borders from the terrorist threat. Without this committment it's moot to discuss which group should defend our borders.
