Then a man named Sukhwinder came to town in November. He says he had just come back from America. He dressed the part, with designer jeans, distinct T-shirts and "fancy sunglasses." He even talked the part, sporting close to an American accent. He says he could help college grads find a job in a big American city for a big engineering firm. Ears perked up when he mentioned Austin as a possible destination. LINK

THE JUSTICE DEPARTMENT The new York Times' Charlie Savage: " Justice Dept. Seeks To Curtail Stiff Drug Sentences" In a major shift in criminal justice policy, the Obama administration will move on Monday to ease overcrowding in federal prisons by ordering prosecutors to omit listing quantities of illegal substances in indictments for low-level drug cases, sidestepping federal laws that impose strict mandatory minimum sentences for drug-related offenses. Attorney General Eric H. Holder Jr., in a speech at the American Bar Association's annual meeting in San Francisco on Monday, is expected to announce the new policy as one of several steps intended to curb soaring taxpayer spending on prisons and help correct what he regards as unfairness in the justice system, according to his prepared remarks.
