Obama administration creates new unit to target major companies hiring undocumented workers; the new unit, composed of fifteen auditors, will work under the supervision of ICE; in 2010, ICE conducted nearly 3,000 audits that led to a record $7 million in fines on companies; critics say large companies mostly avoided prosecution; this new unit will work specifically to audit large companies

Delvonte Tisdale, 16, snuck into the wheel well of a U.S. Airways flight from Charlotte, North Carolina, to Boston; when the plane landed at Logan, his mutilated body fell onto the tarmac; law enforcement officials say they do not know how Tisdale was able to evade airport security; Tisdale’s family is moving to sue the TSA for negligence

Kentucky and Nebraska have introduced tough Arizona-style immigration laws; critics hold that these laws violate civil liberties and encourage racial profiling; more states will likely pass similar immigration enforcement bills; a federal court has already struck down the most controversial portion of the Arizona immigration law and the Department of Justice is challenging it; paradoxically a majority of Americans support stricter enforcement and a path to citizenship

A total of 34,612 people have died in drug-related killings in Mexico since December 2006; the four-year figure included 30,913 execution-style killings, 3,153 deaths in shootouts between gangs, and 546 deaths involving attacks on authorities; the killings reached their highest level in 2010, jumping by almost 60 percent to 15,273 deaths from 9,616 the previous year

A U.S.-Mexico border crossing in Texas’ Big Bend National Park that was once popular among U.S. tourists and Mexican shoppers will re-open in April 2012; the unmanned port of entry will be monitored by immigration officials hundreds of miles away. U.S. citizens will scan their passports and the identity of Mexican nationals will be biometrically confirmed

Mexico’s drug violence in 2010 was striking not only for its scale but also for its brutality; more than 13,000 people were killed across the country in drug violence, up from an estimated 9,600 a year earlier; the number of people killed since the government launched its war on the drug cartels in December 2006 has reached 31,000; analysts say that the violence is the result of the collapse of the old political structure — the 80-year one-party system ran by the PRI, which came to an end in 2000, when Vicente Fox came to power; the old system, with its unwritten rules and tacit understandings, is yet to be replaced by a new, consensual system; what has exacerbated the anarchical situation are two new elements: the rise of drug trafficking through Mexico, and the free flow of arms into the country, mostly from the United States

Mexico, reeling under the weight of the escalating armed conflict between the government and the drug cartels, is on the verge of becoming a failed, ungovernable state on the U.S. door-step; U.S. and Mexican experts say that 90 percent of the tens of thousands of the semi-automatic rifles in the arsenals of the cartels are smuggled from the United State; the Bureau of Alcohol, Tobacco, Firearms and Explosives has announced a new measure, requiring U.S. gun dealers to report multiple sales of rifles to authorities; Texas law enforcement authorities say that since the reporting requirements will only include the southwest border states of Texas, New Mexico, Arizona, and California — guns will continue to flow into Mexico from other parts of the United States — and from other countries

Incoming Republican congressional leaders have plans of their own for border and workplace enforcement; Obama says he still has hope for a path to citizenship for at least some illegal residents; incoming chairmen Peter King (House Homeland Security Committee) and Lamar Smith (House Judiciary Committee) say they have different priorities on immigration than the Obama administration

Governor David Patterson of New York has pardoned six immigrants facing deportation because, he says, deportation is unjustified in their cases; “[immigration officials] may take no account of the New York State criminal justice decisions, but I do,” he said; the Supreme Court is set to hear arguments on the first of two controversial Arizona immigration law; this law was signed by then governor Janet Napolitano, now DHS secretary in the administration which is challenging the law in court
