WASHINGTON — The FBI is joining the Bush administration's war on pornography, and it's looking for a few good agents.

Last month, the bureau's Washington Field Office began recruiting for a new anti-obscenity squad. Attached to the job posting was a July 29 Electronic Communication from FBI headquarters to all 56 field offices, describing the initiative as "one of the top priorities" of Attorney General Alberto Gonzales and, by extension, of "the Director," Robert Mueller.

The new squad will divert eight agents, a supervisor and assorted support staff to gather evidence against "manufacturers and purveyors" of pornography — not the kind exploiting children, but the kind that depicts, and is marketed to, consenting adults.

Mischievous commentary began propagating around the water coolers at 601 Fourth St. N.W., where the FBI's second-largest field office concentrates on national security, high-technology crimes and public corruption.

"I guess this means we've won the war on terror," said one exasperated FBI agent, speaking on condition of anonymity because poking fun at headquarters is not regarded as career-enhancing. "We must not need any more resources for espionage."

Among friends and trusted colleagues, an experienced national-security analyst said, "It's a running joke for us."

A few of the printable samples:

"Things I Don't Want On My Résumé, Volume Four."

"I already gave at home."

"Honestly, most of the guys would have to recuse themselves."

Federal obscenity prosecutions, which have been out of style since Attorney General Edwin Meese in the Reagan administration made pornography a signature issue in the 1980s, do "encounter many legal issues, including First Amendment claims," the FBI headquarters memo noted.

Applicants for the porn squad should therefore have a stomach for the kind of material that tends to be most offensive to local juries. Community standards — along with a prurient purpose and absence of artistic merit — define criminal obscenity under current Supreme Court doctrine.

"Based on a review of past successful cases," the memo said, the best odds of conviction come with pornography that "includes bestiality, urination, defecation, as well as sadistic and masochistic behavior." No word on the other kinks that helps make porn a multibillion-dollar industry.

Popular acceptance of hard-core pornography has come a long way, with some of its stars becoming mainstream celebrities and their products — once confined to seedy shops and theaters — being purveyed by upscale hotels and most home cable and satellite television systems. Explicit sexual entertainment is a profit center for companies including General Motors and Rupert Murdoch's News Corp. (the two major owners of DirecTV), Time Warner and the Sheraton, Hilton, Marriott and Hyatt hotel chains.

But Gonzales endorses the rationale of predecessor Meese: that adult pornography is a threat to families. Christian conservatives, long skeptical of Gonzales, greeted the pornography initiative with what the Family Research Council called "a growing sense of confidence in our new attorney general."

Congress began funding the obscenity initiative in fiscal year 2005 and specified that the FBI must devote 10 agents to adult pornography. The bureau decided to create a dedicated squad only in the Washington Field Office.

"All other field offices may investigate obscenity cases pursuant to this initiative if resources are available," the directive from headquarters said. "Field offices should not, however, divert resources from higher priority matters, such as public corruption."

Public corruption is fourth on the FBI's priority list, after protecting the United States from terrorist attacks, foreign espionage and cyber-based attacks. The memo from headquarters does not mention where pornography fits in.

FBI spokeswoman Debra Weierman expressed disappointment that some colleagues find grist for humor in the new campaign. "The adult obscenity squad ... stems from an attorney-general mandate, funded by Congress," she said. "The personnel assigned to this initiative take the responsibility of this assignment very seriously and are dedicated to the success of this program."
