So we apparently building a fence along the Mexican border to stop or slow down illegals. Well its seems they have been adapting. The drug dealers have been digging tunnels for years and more are being discovered.
It doesn't appear to me that we are winning the war on drugs. The number 1 drug being smuggled is Marijuana. IMHO, pot needs to be legalized, especially for those that need it for medicinal purposes. Pot could be taxed, which would bring in more revenue for states.
I guess if you don't agree, than maybe we should dig a moat.
