I don't think anyone has ever claimed a wall would replace the Border Patrol and 100ft is an exaggeration a liberal would use to try to make people in favor of a wall look silly. I would imagine 20' or 30' would be sufficient if you had a few LEOs watching for herds of ladder toting beaners approaching, and a extra hot hot wire on top. I bet a few of would still outsmart you, but I don't think a few million a year could, if you had a wall that is.
Honest question. Why do you think people who live many hundreds, or thousands, of miles away from the border think it's the answer to all their ills, but people who live relatively close think it's a dumb idea?
