I don’t disagree with you, but you’re citing evidence about a wall that is located in one of the most heavily populated areas of the border where there are a number of border crossings and Border Patrol scrutiny is already very heavy.
it’s a hundred miles of wall and not all of it is in a populated area.
Border Patrol Agents agree across the board that walls work. They are effective. Very few will get through and those few will have the Border Patrol in pursuit.
