On this side of the border, in places like Dallas and Phoenix, there is evidence the violence is spilling over. Meanwhile, a big U.S. aid package is in the works to pump up the Mexican governmentâ€™s war on the cartels. Some call it "Plan Mexico," after Americaâ€™s earlier gung-ho drug intervention, "Plan Colombia."
