Washington-most of the top investigators of an elite Mexican police unit that was trained by Americans may have ties to drug traffickers,U.S. officials say.The disclosure threatens to undermine an ambitious effort to overhaul the deeply corrupt law enforcement system of Mexico. U.S. government experts traveled to Mexico late last month to administer routine lie-detector tests to dozens of police agents. Now officials say some investigators who failed had been chosen for their posts after elaborate U.S. designed screening. U.S. officials said they were just beginning to assess the damage that corrupt investigators might have wrought, a task that could take months. Most senior officials in the unit were implicated by the lie-detector tests. But already, officials are saying that much of the sensitive information that U.S. law-enforcement agents shared with Mexican counterparts over the past year may have been compromised. "You have to assume that everything we've been giving them has ended up in the hands of the traffickers," said a senior U.S. law-enforcement official who, as did others, insisted on anonymity. "It's a disaster." Mexican officials are expected to undertake their own inquiry into the case, which involves a force called the Organized Crime Unit, set up 18 months ago. Some Mexican officials have challenged the lie-detector tests, U.S. officials said. The penetration of the unit, apparently by powerful drug gangs, is the latest in a series of such calamities. For 10 years, as successive administrations in Washington have sought to work more closely with the Mexican authorities, U.S. officials have publicly embraced senior Mexican prosecutors, police commanders and other officials who have later been revealed to have taken bribes from major drug smugglers. In the most serious case, the Mexican government announced last year that its drug-enforcement chief was in fact working secretly with the man then considered the biggest cocaine trafficker in the country, Amado Carrillo. Days earlier the official, Gen. Jesus Gutierrez, had been basking in the praise of the Clinton administration's drug-policy director, Gen. Barry McCaffrey. McCaffrey and other administration officials vowed that such a debacle would not occur again. They pressed for a sweeping reorganization of how the United States gathers and disseminates intelligence about trafficking. The reorganization plans have run into wide opposition among Mexican law-enforcement officials. But more important for Mexico, U.S. law-enforcement officials also provide extensive help in writing a new law against organized crime, in setting up an investigative unit to enforce the law and in screening hundreds of police agents assigned to drug enforcement. Prospective members of the Organized Crime Unit were submitted to extensive background and financial checks, lie-detector tests and psychological evaluations. Nearly all those chosen also received training from the FBI, the Drug Enforcement Administration or both. But after a year and a half, during which the team of 70 investigators, prosecutors and intelligence analysts has been responsible for investigating many of the most important drug-trafficking and kidnapping cases, its record is mixed. Mexican and U.S. officials praise the unit for what they say was its leading role in the arrests of a handful of important smugglers and the dismantling of a kidnapping ring that terrorized central Mexico while receiving protection from state official. In particular, Samuel Gonzalez Ruiz, 38, a former university professor who heads the unit, has won wide respect from U.S. officials for what they say is honesty and courage. Gonzalez Ruiz was one of three top unit officials who were said to have passed the lie detector tests. Increasingly, though, U.S. officials have grown critical of the unit for failing to capture leaders of the biggest trafficking gangs, despite having access to some of the most sensitive intelligence that Washington has ever given the Mexican government. - --- Checked-by: Pat Dolan
