Trump tryingg to protect us from the southern border is so much like Wile E. Coyote trying to catch the Roadrunner. First he wants to build a wall, & he comes up with this cheesy ACME version that blows down in a high wind (thanks, climate change). Now he's looking into building a 2,000 mile moat along the border & fill it with snakes & crocodiles (can you say "row boat"?).
Simpler to fix the cross-border crime that makes the border so dangerous to begin with.
