Some San Diegans are taking a new approach to fighting illegal immigration. A local monthly paper has started a registry of local businesses that have pledged to hire only authorized workers. As the introduction to the registry says, “When the government refuses to enforce our employment laws, the only alternative is self-enforcement by the consumer.” A great idea that could be taken nationwide, with stickers issued to participating employers: “We Employ Only Americans and Legal Immigrants!” But would it be so much to ask that these people get a little help from those who have sworn an oath to uphold the Constitution and the laws of the United States?
