Guess who is behind Arizona's immigration law?

In an example of fine investigative reporting (again illustrating the problem of private media and demonstrating the necessity of public media), NPR shows who is really behind the new immigration law in Arizona.

The lesson of this story is simple: If private companies wrote this law, because they thought it would benefit them personally (i.e., financially), then they clearly do not really want illegal immigration to go away. How do we know? Because they are in the business of making money; thus they would not write and push a law that would lead to monetary loss.

Translation: As long as there is illegal immigration, private prisons will make money. That is the clearest proof that the Arizona immigration law (written by the private prison industry) will not reduce illegal immigration into the country.
