The spectacular nationwide response to the killing of another Mexican drug lord should be analyzed as the possibility of a class struggle response versus simply criminal activity coast to coast! The two nations will never end the cartels market until they reduce poverty.
Look at Canada, it is on the border with the US why doesn't it export large amounts of drugs because it's population is more prosperous and educated!
America will continue to use so much drugs because SO MANY AMERICANS ARE POOR and see little hope for progress.
It should be noted that China traditionally had many corrupting criminal organizations. So today China's PUBLIC SECURITY BUREAU is a massive organization with more personnel than the US FBI, CIA ,NCIS DIA etc! So for Mexico to put it's law enforcement house in order like China it will need to build a similar, massive state security organization at the expense of democracy!
Few Americans realize that Trump is trying to build a massive state security agency like the former Soviet KGB by combining Homeland security,local police, border patrol, FBI, and others to reach coast to coast! The sophistication of modern crime seems a necessary excuse to ignore Democracy.
