Doesn't matter if I can climb it. It was sold as unclimbable. That just isn't the case.
No one ever sold it is unclimbable. That is total bullshit as always. The very best prisons are broken out of, the very best walls, scaled. The point is that you are not going to get over it unless you are young, fit, very determined, and make a concerted effort likely with some sort of big ladder or other special gear or help. Or you will try digging under it.
Women and children and older men won't be getting over it. It will take planned, organized effort and hordes of caravans are not going to just waltz in. Meantime, while they are doing all that, they will be spotted by a camera or passing patrol. Personally I don't like the design, I would have gone another way, at least 5 feet taller too, but I realize there is an economy here, and part of that is the trouble Trump has had getting the Congress to give him the funding he needs.
So if the wall is climbable by 1-5% of the attempted illegal invaders, you can lay the blame squarely at the feet of the Democrats, for had they allocated the 20B, Trump could have certainly gone deluxe.
