"Wouldn't it be easier to just seal the border?"

Do you have a clue as to what the Arizona-Mexico border looks like? It is a few hundred miles of mountainous crags with extreme weather conditions and virtually impassible even by horse. Would you like to try it?

I wish your description matched where I live, but unfortunately the mountain ranges here in Cochise County run north to south and most of the border is flatlands with hundreds of arroyos offering near perfect concealment to border crossers. It's just a step shy of being trench warfare. At eye level, you could have fifty illegals a hundred yards away and never know it.
