Even those who are appalled by Arizona's harsh new immigration law -- as we are -- recognize that the state's misguided decision to take federal matters into its own legislative hands did not come out of the blue. Arizona is the preferred superhighway for drug and human smugglers. Phoenix is the kidnapping capital of the nation, and almost all of those abducted are either illegal immigrants or linked to the drug trade. The recent killing of a rancher in southern Arizona has increased the sense of lawlessness and danger at the border; police believe the killer was involved with drug trafficking. Fed up with federal inaction, Arizona lashed out.
