First, we may be able to significantly reduce the amount of drugs coming in by using a state-of-the-art Barrier system that includes walls, fences, sensors, etc. far more robust than we have now; However, I believe we never will fully stop the infiltration of drugs into the US. There are far too many ways drugs can be smuggled -- tunnels, boats, ships, submarines, aircraft, catapults, etc. to name only a few.
Second, as a libertarian, I believe that people should have the maximum degree of freedom and liberty as possible to do what they choose to do as long as their actions do not hurt others. Along with that freedom comes personal responsibility and full accountability for our actions. If I choose to use heroin, cocaine, methamphetamine, flacca, or any other illegal drug, I should have that freedom but also be fully accountable for my actions. Our American society should have no responsibility to save me from myself. If I live a horrific life or kill myself as a result of my choices -- so be it.
I support a "Wall," or what I refer to as a barrier because I believe we need to better control our borders, reduce or eliminate illegal immigration, prevent entry to the US by terrrorists and criminals, and prevent the possible importation of weapons -- particularly large quantities of explosives or heavy weapons, and most specifically nuclear, radiologic, chemical, or biologic weapons.
At the same time, I support robust legal immigration and guest-worker programs, as long as they are in the best interests of our nation.
