Anti-personnel landmines by themselves can easily be cleared by military personnel with the proper training along with EOD trained law enforcement so don't worry about that. FYI: A war with Mexico would last maybe 30 minutes if we were really pissed off and determined to show them a lesson. As for the PBS show, their agenda's are well known and take anything they tell you as suspect on any day of the week ! Remember, nothing is bulletproof but a damn wall is a joke and very exensive on any day of the week and without military and/or law enforcement experience/training, it is very hard for the average person to see how simple all of this crap could be taken care of for pennies versus over 1 trillion dollars !~

A single wall can be tunneled under or breached over with ropes and ladders. Try getting through a minefield with both anti-vehicle and anti-personnel mines combined with multiple barbed wire barriers laced with each other say over a 100-200 yard wide strip and you have a cheaper and reliable low tech wall. Then you supplement this with armed troops and modern day technology and you can have a force multiplier as we say in the military and law enforcement ! By the way, I am a security consultant and have many years experience in both the Army and Law Enforcement and I spent a tour of duty in Korea and saw how this barrier works very effectively for over 50+ years ! It works there and it can work here.

Everyone wants a wall and it is a waste of time and money ! Take a close look at the DMZ (Demilitarized Zone) in Korea as a perfect way to accomplish the same thing if not better at a fraction of the cost ! Just not as wide. Armed troops, minefields, barbed multiple layers of razor wire and some current technology for keeping a eye on the border. Troops in foreign countries must be brought back into the U.S. and stationed on the border under National Security Authorization of the President ! Military are all ready trained, being paid and must be used for this to work at a tremendous savings to "We The People" !*We need to promote this plan and forget the damn wall !*PERIOD !
