townhall.com | Mexican President Felipe Calderon has accused Arizona of opening the door "to intolerance, hate, discrimination and abuse in law enforcement." But Arizona has nothing on Mexico when it comes to cracking down on illegal aliens. While open-borders activists decry new enforcement measures signed into law in "Nazi-zona" last week, they remain deaf, dumb or willfully blind to the unapologetically restrictionist policies of our neighbors to the south.

The Arizona law bans sanctuary cities that refuse to enforce immigration laws, stiffens penalties against illegal alien day laborers and their employers, makes it a misdemeanor for immigrants to fail to complete and carry an alien registration document, and allows the police to arrest immigrants unable to show documents proving they are in the U.S. legally. If those rules constitute the racist, fascist, xenophobic, inhumane regime that the National Council of La Raza, Al Sharpton, Catholic bishops and their grievance-mongering followers claim, then what about these regulations and restrictions imposed on foreigners?

-- The Mexican government will bar foreigners if they upset "the equilibrium of the national demographics." How's that for racial and ethnic profiling?

-- If outsiders do not enhance the country's "economic or national interests" or are "not found to be physically or mentally healthy," they are not welcome. Neither are those who show "contempt against national sovereignty or security." They must not be economic burdens on society and must have clean criminal histories. Those seeking to obtain Mexican citizenship must show a birth certificate, provide a bank statement proving economic independence, pass an exam and prove they can provide their own health care.

-- Illegal entry into the country is equivalent to a felony punishable by two years' imprisonment. Document fraud is subject to fine and imprisonment; so is alien marriage fraud. Evading deportation is a serious crime; illegal re-entry after deportation is punishable by ten years' imprisonment. Foreigners may be kicked out of the country without due process and the endless bites at the litigation apple that illegal aliens are afforded in our country (see, for example, President Obama's illegal alien aunt -- a fugitive from deportation for eight years who is awaiting a second decision on her previously rejected asylum claim).

-- Law enforcement officials at all levels -- by national mandate -- must cooperate to enforce immigration laws, including illegal alien arrests and deportations. The Mexican military is also required to assist in immigration enforcement operations. Native-born Mexicans are empowered to make citizens' arrests of illegal aliens and turn them in to authorities.

-- Ready to show your papers? Mexico's National Catalog of Foreigners tracks all outside tourists and foreign nationals. A National Population Registry tracks and verifies the identity of every member of the population, who must carry a citizens' identity card. Visitors who do not possess proper documents and identification are subject to arrest as illegal aliens.

All of these provisions are enshrined in Mexico's Ley General de Población (General Law of the Population) and were spotlighted in a 2006 research paper published by the Washington, D.C.-based Center for Security Policy. There's been no public clamor for "comprehensive immigration reform" in Mexico, however, because pro-illegal alien speech by outsiders is prohibited
