High crime rates by air marshals

Shawn Nguyen bragged that he could sneak anything past airport security using his top-secret clearance as a federal air marshal. And for months, he smuggled cocaine and drug money onto flights across the country, boasting to an FBI informant that he was "the man with the golden badge."
Michael McGowan used his position as an air marshal to lure a young boy to his hotel room, where he showed him child porn, took pictures of him naked and sexually abused him.
And when Brian "Cooter" Phelps wanted his ex-wife to disappear, he called a fellow air marshal and tried to hire a hit man nicknamed "the Crucifixer."
Since 9/11, more than three dozen federal air marshals have been charged with crimes, and hundreds more have been accused of misconduct, an investigation by ProPublica, a non-profit journalism organization, has found. Cases range from drunken driving and domestic violence to aiding a human-trafficking ring and trying to smuggle explosives from Afghanistan.

Before 9/11, the Air Marshal Service was a nearly forgotten force of 33 agents with a $4.4 million annual budget. Now housed in the Transportation Security Administration, the agency has a $786 million budget and an estimated 3,000 to 4,000 air marshals, although the official number is classified.

Since 9/11, air marshals have taken bribes, committed bank fraud, hired an escort while on layover and doctored hotel receipts to pad expenses, records show. They've been found sleeping on planes and lost the travel documents of U.S. diplomats while on a whiskey-tasting trip in Scotland.
