My thoughts were: we have a coast gaurd, why not a border guard. Who's main military roles is one of protection and police inside of a "border zone," rather than place kill-em-all army types. I think this is EXACTLY the way the army should be, but I don't think the army's mission coincides with a police action on the border
From Brownsville Texas to San Diego Calf.? This strikes me as 1 silly 2 futile 3 Not gonna happen.
Look, if we wanted to build a fence that long and police it with a real armed force we could do it. Don't kid yourself. If we really want to keep them from crossing the border, that's how we make sure. I agree with point 3 - it's never going to happen. But, the last time I checked, no one in power was asking me :-)
