Calderón had tried to sell his “war on drugs” by insisting that he is waging it to “save our children.” If that connection proves faulty, it will not work, and Mexicans may question the point of a “war” that has more than doubled the number of gangland executions, from 2,000 in 2006 to 5,000 in 2008, when their children, statistically at least, are not in harm’s way.
