Here’s a root of evil: American users of illegal drugs. It is reported they spend $40 billion a year on their addiction. These billions finance the drug cartels in Latin and South America which dominate those governments and are currently taking over Mexico because they have more and better fire power than the local or federal governments. These ruthless people kill judges, news reporters and political candidates who campaign against them and corrupt law enforcers on both sides of the boarder; the leaves from these branches of evil are now blowing across our entire border with Mexico, and no fence or patrol will stop them because the cartels know what their American customer wants and will find a way to deliver the goods. Attack the root (the drug user’s addiction) and the leaves will wither.
