In my talk, I pointed out that America's system of immigration controls necessarily comes with an immigration police state. Since I grew up in South Texas and practiced law there for eight years, I lived under that immigration police state for much of my life. 

That's an important point for libertarians to note, especially because there have long been conservative-oriented libertarians who spend a lot of time and effort trying to persuade libertarians to abandon their position in favor of open borders and join the statist position of government-controlled borders. At the risk of belaboring the obvious, an immigration police state is not something that is consistent with libertarian philosophy, which is grounded in liberty and limited government.

As I also pointed out in my PorcFest talk, a system of immigration controls also brings into existence a culture of death. Every year, hundreds of people die because of America's system of immigration controls. 

The latest example of America's culture of immigration death involves 46 immigrants in San Antonio. Their bodies were found in the back of a tractor-trailer. They had died of dehydration in the blistering South Texas heat.

Needless to say, there have been the standard expressions of outrage and sorrow over the deaths. According to the Los Angeles Times, San Antonio Mayor Ron Nirenberg called the deaths "nothing short of a horrific tragedy." San Antonio City Councilwoman Adriana Rocha Garcia said, "These families, I can't imagine what they're going through, not knowing if their family member was one of the ones who passed away. All they were doing was trying to come for a better life."
