On top of the steady state mayhem in the US and Mexico from the drug trade, there was an uptick in mayhem this week with the arrest of "El Huevo," the leader of the latest successor to Los Zetas.
Clearly it is the illegalization of drugs that makes them profitable.
In the present paradigm, drug addicts and profiteers not only injure themselves, but us (theft, political corruption, and violent crimes).
One is tempted to look at alcohol prohibition and to notice the fall in violence when prohibition ended, but the profiteers moved into other prohibited substances with increased profit and an eventual return to criminal violence.
Jesus assured us we would always have the poor. It seems to be that, implicit in His warning, is a recognition that we will always have criminals (and self-destructive people).
It seems worth considering that confining the problem is more likely to be successful than eliminating the problem.
I welcome suggestions from reasonable people here.
