You don't have to add agents if youuse the military already on the payroll.
I have used this argument numerous times and the reason it is rejected is that it is logical to begin with, and provides a laboratory to perfect and hone the skills a soldier needs to be an effective deterrent force. By normal rotation of troops on and off the borders north and south we get a much better use of our tax revenues. Ft. Hood for example is a superior marshalling center to supply all the needed numbers to achieve this vital training and preparation. As usual the chances of this happening are like the proverbial "SNOWBALL"! If it is not "OFF THE WALL" nobody will give it a second look!
