David Cook Martin did not present a single argument on why he claims the Wall with Mexico Won't Work. 
*
His only argument is the conclusion "No wall can change these facts."  Except those facts have nothing to do with How or Why the Wall with Mexico won't work
*
Trump boost border patrol numbers which with the Wall may put a halt to the flow of illigals to the US across the US-Mexico border.
*
Martin failed to mention that Trump intends to complete the biometric entry-exit visa tracking system to catch overstaying visa holders to rebut his minimizing the importance of the wall with this claim - as many as half of unauthorized immigrants in the U.S. are people who overstay their visas, not border crossers - which is irrelevant to how or why the Wall won't work.
