What President Trump should consider about securing America's borders is not a wall on their southern border with Mexico but my alternative. I saw a program this afternoon on CNN that showed how porous the border can be in areas, like the the Rio Grande. A night vision camera witnessed long lines of illegals carrying large boxes on their backs (drugs) into the United States. Also other unprotected areas with people just walking across. 

Then the idea hit me. Land mines. Never mind an expensive fence you could booby trap the border really good, especially put some of those anti tank mines in with a mix of anti personnel. Sure you would have to reconfigure the detonating mechanisms on the big ones so a human would set it off but no real problem there.  A few of those human traffickers or drug smugglers get blown to kingdom come and the deterrence effect would be brilliant. Those waiting back of the line would hear the big booms and high tale it south!
