Most libertarians are coming out against the Arizona bill. I have been saying we have to observe the rule of law and it is illegal for immigrants to come here without going through a proper procedure. We have the right to know that new people are not running from the law, carrying drugs, or on some terrorist watch list. We welcome those who want to do things the right way.
I am not the only one.
Part of the Summation from Hyscience:
... the central fact that rule of law is necessary in creating a free society. If we didn't appreciate the role of law and order in protecting civil liberties, we'd be anarchists. A free society can not exist in a world where the law of the land is routinely flaunted and the responsible government authority merely shrugs. A free society depends on a limited government that proactively fulfills the few responsibilities it does have, and the Arizona bill is nothing short of the people of Arizona twisting the arm of the federal government to get it to live up to its responsibilities.
We can and will find a compromise to this issue. But our soverienty must be protected in the process.
