Kris Kobach, the author of the new Arizona immigration law, explains what it actually says, something few people have bothered to note.
[The law] prohibits the harboring of illegal aliens and makes it a state crime for an alien to commit certain federal immigration crimes. It also requires police officers who, in the course of a traffic stop or other law-enforcement action, come to a “reasonable suspicion” that a person is an illegal alien verify the person’s immigration status with the federal government.
He also explains why it’s necessary:
Arizona is the ground zero of illegal immigration. Phoenix is the hub of human smuggling and the kidnapping capital of America, with more than 240 incidents reported in 2008. It’s no surprise that Arizona’s police associations favored the bill, along with 70 percent of Arizonans.
