"This wall, you won't be able to touch it. You can fry an egg on that wall — it's very very hot," the president told reporters in Otay Mesa, in the San Diego sector of the U.S.-Mexico border. "So if they're going to climb it, they need to bring hoses and water and I don't know where they're going to hook it up. There's not a lot of water out here."
- Active or passive automated defense from the wall? Why not have it create heat to burn people. Electrify? Auto-turrets? (Makes me think of an Aeon Flux episode.)
- Water? Or gloves.
