Hey, Juan, doesn’t it make sense that if a wall is built more resources can be devoted to port inspections?
The CBP x-rays, dog searches and puts aside for further inspections those who raise suspicion. They do it for walkers and vehicles. They do it as they cross and again at BP checkpoints further in.
The majority of drugs are backpacked in by illegal crossers who climb the high metal fences and walls, the three wire fences or metal pole fences or, at the Rio Grande, in boats all outside of the ports of entry.
The propaganda in this country is out of control.
Google Earth the Border. Inform yourselves and your family and friends. There are hundreds of miles between designated border crossings.
