CNN Lou Dobbs - video:Chertoff: "Illegal Immigration so far has Defeated all the Enforcement Measures"Homeland Security Secretary Michael Chertoff gave a bleak assessment of our ability to secure our southern border. Secretary Chertoff said illegal immigration so far has defeated all the enforcement measures this government has been able to muster. "Only a temporary worker program will give us the ability to deal with that tremendous economic draw which has time and again over the years defeated all of the enforcement measures that the government has placed on the border to try to get security for this country," he said. But Dan Stein of the Federation for American Immigration Reform argues that a guest worker program could make the problem of illegal immigration worse. "If we're not prepared to put in place the resources needed to make sure aliens leave when they're supposed to, to ensure employers can only hire lawfully authorized workers, to make the law have credibility again, nothing about a guest worker amnesty plan is going to make that a reality. Our borders will be out of control and our national security and our communities will be in jeopardy." A recent DHS report to Congress which said the department has effective control only 15 percent of the southern border.
