Yeah, the key to using a wall for security is that the wall has lookout towers and there are people in those towers, looking out. Take the massive consensus of experts who say the border wall won’t work and asking them, “what if there were towers that had a minimum of two lookouts per tower 24/7 every two hundred feet” and they’d probably all say, “Oh, yeah, then, that would work fine… how much is that going to cost?!?” That said, I think I’ve thought of a new way to pitch the Green New Deal’s full employment clause that could get Trump on board…
And my guess was it would be defeated by a person who pushed really hard because what looked like concrete was actually hollow drywall and what looked like the budget for concrete was actually in Trump’s pocket.
