Let me present what I think are the legitimate arguments on each side, and then present what how I think the scientific theory of porosity should be applied to developing a rational and reasonable policy.
Before I start, I must say I’m married to a legal immigrant, born in Peru but now a naturalized American citizen (with a US passport to prove it!). My in-laws who live in the US are all here legally (e.g., my mother-in-law has her green card to prove it). What I have found that it’s much easier for us as Americans to travel to Peru to visit the relatives than it is for some of them (particularly children and teens) to get tourist visas to visit us here.
The Border in Arizona
Simply put, the border in Arizona is quite porous and illegal crossings occur daily. But more troublesome is the drug trafficking and associated crimes including murders of citizens and law

All sides agree that it is the Federal government’s sole responsibility to regulate immigration and border crossings. But, many have noted that for decades now, the Federal government has not done enough to control the border in Arizona. In some places (such as San Ysidro, CA Tiajuana, Mexico), there are walls, border patrols and designated entry points where documents are checked. But in other places, particularly remote areas, there is little in the way to prevent entry into the US.
The proponents of the new law say that it is needed because the Federal government did not do its job regarding controlling the border.
What Does a Person Suspected of Being Illegally in the US Look Like?
The gist of the opposition to the new law deals with how it might be enforced. In particular, how does a law enforcement officer come to have reason that someone may be illegally here?
So let’s be frank. While the law prohibits “profiling” and the law’s supporters say there will be no profiling, I still ask myself, how does an officer come to suspect someone in the US illegally? If it’s not by skin color, or accent or language, what is it? Sure, some people might look suspicious, like they’re trying to hide something or fleeing when they see the police approaching.

But here’s the problem for libertarians: what about American citizens who “look foreign” (to be frank, who look Hispanic or Latino). Some may be naturalized citizens, others born here, and others may be American citizens for generations. But they may still look like people who may be in the US illegally. Will this subject American citizens to have to prove they are Americans?
Now the politicians and supporters will tell us this won’t be the case or this isn’t a problem. But, let’s be real. It will happen from time to time. And this is a slippery slope from asking a few Hispanic Americans citizens in Arizona to prove they belong here toward having a national identity card or similar way for big government to check on us, even if we’ve done nothing wrong. To me, asking even a few American citizens in Arizona to “show us your papers” is something that reeks of Nazi Germany and other repressive regimes.
The New Libertarian Socialist View of Immigration
Let me digress to present the origins of my beliefs as a “new libertarian socialist.”
The Christian Socialist view sees the immigrant as the stranger whom we should welcome, much as Christ said that we welcome him when we welcome the least among us who is a stranger in our land. This view is also not embraced by supporters of the new law. What is lost in the rhetoric is that even those here illegally are human beings, and like all humans they are created in the image of God.
I think most people agree we have a mess in the border states. Immigration is out of control. This is the Federal government’s job and it’s not been done.
I think there is a majority who would like to see the current mess transformed into a situation where those in the US who are not citizens are here legally. This would be accompanied by reasonable controls to allow a number of legal immigrants to fill jobs where there is a need. And, this would also provide the protection of the law for those non-citizens who are here legally. These legal immigrants would pay taxes and need not fear law enforcement officers as they would have the documentation to prove their legal status.
