president trump in san diego just a few moments ago. so we re looking at the wall and the wall systems and we have a lot of them. and this gentlemen who s a real expert, you ve been doing this how long? 25 years, sir. and you were here before they had a wall? correct. i started here in 1992. and what was it like until you built the wall? and the wall, by the way, is that wall up there, which is just sheet metal, but still, at least it works a little bit. how was it before you built a wom wall? there was effectively no border in san diego. it was a chaotic situation. this fence behind me, it was made out of scrap metal that the military wasn t using that we set in place to really delineate the border. you needed something? it changed our environment. we decreased the illegal cross-border traffic by 95% with that fence and the roads and the lights and the technology so that s 95% with a scrap metal wall that they just put together with excess material
