CNN Lou Dobbs - video:Nashville Joins the Rebellion, Cracks Down on Illegal AliensNashville, Tennessee, is joining the ranks of cities trying to tackle an influx of illegal aliens. The city council is considering three measures. One is an English-first ordinance. And another would hold landlords responsible for renting to illegal aliens. And a third would punish businesses that hire illegals. Now, the proposals must pass one more vote to become law. And such local efforts are deemed necessary because the federal government won't enforce laws already on the books. But in an ironic turn, the feds may be able to overturn what the locals are trying to do in court. as these towns fight illegal immigration on their own, they are faced with massive legal challenges. Challenges that come from a variety of legal activists, including the American Civil Liberties Union, the Puerto Rican Legal Defense and Educational Fund, and the Mexican-American Legal Defense and Educational Fund. Kris Kobach of the Immigration Reform Law Institute said: "Unlike so many small towns and cities across America over the past few decades that have rolled over whenever the ACLU marched in town with their legions of attorneys, these towns, Hazleton, Pennsylvania; Valley Park, Missouri; Escondido, California, have said, no, we're going to fight, we're going to pay the cost." Hazleton has only a half a dozen lawyers on its side, standing against 24 in opposition in its ordinances to fight illegal immigration. The mayor of Hazleton says he's committed to taking the fight to the Supreme Court of the United States if necessary in an effort to affirm the town's right to impose sanctions based on federal laws.
