Bribery of federal and local officials by Mexican smugglers is rising sharply, and with it the fear that a culture of corruption is taking hold along the 2,000-mile border from Brownsville, Texas, to San Diego.

At least 200 public employees have been charged with helping to move narcotics or illegal immigrants across the U.S.-Mexican border since 2004, at least double the illicit activity documented in prior years, a Times examination of public records has found. Thousands more are under investigation.

Criminal charges have been brought against Border Patrol agents, local police, a county sheriff, motor vehicle clerks, an FBI supervisor, immigration examiners, prison guards, school district officials and uniformed personnel of every branch of the U.S. military, among others. The vast majority have pleaded guilty or been convicted.

Though America’s southern border may evoke images of a poor backwater, it is alive with vast amounts of ill-gotten wealth, shadowy organizations that ply the waters of the Rio Grande, and brazen schemes that seem borrowed out of Cold War espionage.

Paul K. Charlton, U.S. attorney for Arizona since 2001, is convinced border corruption is worsening — and jeopardizing the trust that U.S. communities place in their government.”The concern for me is that we can very quickly develop a culture that would be more accepting of that kind of misconduct,” Charlton said. “You only have to look south of the border to see what happens when a certain level of corruption is accepted.”

Officials warn that the risk of public corruption will grow as Congress and the Bush administration respond to public demands to improve border security. Customs and Border Protection, a part of the Department of Homeland Security, wants to add 10,000 employees to its workforce of 42,000, most of whom are already stationed along the Mexican border.

“If you increase the number of people on the border, you are going to get more corruption,” said the FBI’s Burrus.

Look who’s in charge of the store! Do you think they’ll apply anything higher than Halliburton standards to the Mexican border?
