Eller, 63, pleaded guilty to making false statements in a matter within a political subdivision, tampering with evidence, hindering apprehension or punishment of a criminal and violation of oath by a public official or officer.

The two deputies, Jessie Gibson, 56, and Chief Deputy Eddie Osborn, 41, faced aggravated assault and obstruction charges in connection with a July 9 shooting at the home of Gary Dean of Hiawassee. Dean, who was not injured, was "involved in an ongoing intimate relationship" with Osborn's wife, according to a Georgia Bureau of Investigation affidavit.

Gibson was found dead on Aug. 8 of a self-inflicted gunshot in what authorities called an apparent suicide.

Outside the courthouse Tuesday, Eller apologized to the residents of Towns County.

He wore an oxygen tube in his nose as he walked from the courtroom. Mike Weaver, his attorney, said Eller was suffering from diabetes and other health problems and could not answer other questions. He said Eller's sentencing is pending.

He was arrested Aug. 13 for investigation of violating the order when he was found near a child care center at the University of California, Los Angeles. He had a camera with him at the time, but he told a local TV station that there wasn't any film in it.

McClellan was arrested again — several hours later — this time for trespassing after he did an interview with the TV station on university grounds. He had been told not to return to the campus after his first arrest. Prosecutors did not pursue the trespassing charges.

Superior Court Judge Melvin Sandvig issued the order Aug. 3 requiring McClellan to stay at least 30 feet away from every person under age 18 in California for a three-year period, said Nick Velasquez, a spokesman for the Los Angeles city attorney's office.

A three-year order amounts to what is termed a preliminary injunction, and cannot be issued without the statutory hearing and notice requirements, according to the city attorney's office.

Superior Court spokeswoman Pat Kelly said Sandvig could not comment because the case is pending. A call to his chambers went unanswered late Tuesday.

A cellphone message left for McClellan was not returned.

McClellan is unemployed and has been living out of his car. He stirred controversy in Southern California when he arrived this summer from Washington state, where he had lived with his parents.

McClellan maintained a website in Washington where he posted photos of children he had taken in public places. He also discussed how he liked to stake out parks, public libraries, fast-food restaurants and other areas where little girls, or "LGs," congregated.

His server took his website down more than a month ago. McClellan, who said he lives on supplemental security income and suffers from depression, has maintained that he launched the site as a form of therapy and wouldn't do anything illegal.

McClellen also has a hearing set for Friday on a temporary restraining order preventing him from coming within 10 yards of children in the city of Santa Clarita in northern Los Angeles County, authorities said.

During a court hearing for Engman's case last week, Schlueter showed a video of a police tactics consultant shocking Engman for a few seconds, in order to demonstrate that Engman's injuries were more severe than those caused in the video. Schlueter and his brother were also shocked in the video, Schlueter said.

But, after the tape was shown, San Bernardino County Deputy District Attorney Dan Ross said that Schlueter and his consultant Roger Clark may have violated the state's human experimentation law, which requires patients to sign waivers for medical experiments, according to Schlueter and local news reports.

When questioned by Ross, Clark testified that he was not certified to use the Taser and that he had not obtained waivers from Engman, Schlueter or his brother.

"It's something we're going to look at," Ross said of filing criminal charges, according to the Inland Valley Daily Bulletin. He declined to comment when contacted by ABC News.

Judge Katrina West postponed the hearing, advised Clark of his right against self-incrimination and appointed an attorney to represent him. She also advised Schlueter of his rights.

Schlueter said the move by prosecutors was an attempt to stop him from showing how police used excessive force on Engman. He said he had to shock Engman because he could not get studies on injuries caused by the weapons from Taser International. "I've never, ever heard of a single case like this," Schlueter said.

Ross told the Daily Bulletin that Clark's experiment damaged his credibility as an expert.

Neil Shouse, a former Los Angeles prosecutor, said the case was "very unusual. & This is first time I've heard of something like this," he said.

The state's human experimentation laws require that subjects of medical experiments be given an explanation of the purposes and risks of any experiment. They must give their written consent to participate. Violations can carry penalties of up to one year in jail or a $50,000 fine.

Alexander Capron, a professor of law and medicine at the University of Southern California, and an expert in medical ethics, said the law, which applies to "medical experiments," was intended to apply to medical research.

Told about Schlueter's case, Capron said, "This doesn't sound like research, as that's usually understood."

"If he's allowing himself to be stunned for the purpose of producing evidence in court, the notion that they're engaged in research seems laughable on its face," he said.

American Airlines (AA) is suing Google Inc over the Internet firm's sale of keyword ads for rivals trig-gered by its own trademarks.

A Google visitor who enters certain words or phrases that AA trademarked -- for example, Aadvantage, the name of its frequent-flier program -- will get links to AA's Web site but also its rivals under "sponsored links" -- targeted ads that appear alongside the regular search results.

Google makes most of its money from such keyword ads.

AA filed a lawsuit on Thursday in US District Court seeking unspecified damages.

"When done right, search is a great tool, but we have a problem with this part of their business," AA spokesman Billy Sanez said.

Sanez said the results could confuse consumers and divert customers away from AA's own site.

American Airlines, a unit of AMR Corp, tried to negotiate a settlement with Google before going to court, Sanez said.

Google spokesman Jon Murchinson said the company is "confident that our trademark policy strikes a proper balance between trademark owners' interests and consumer choice, and that our position has been validated by decisions in previous trademark cases."

Similar lawsuits against Google are fairly common, although they tend to involve smaller companies.

More than two years ago, a federal judge ruled in a similar case filed by insurer Geico Inc, ruling that Google's advertising practices were legal. Geico had said Google was letting rival insurance companies pay to have their ads displayed when a user searched for "Geico."

But the judge left the door open for Geico to collect damages from Google for featuring ads that used Geico's name in the text, rather than just using the trademark to trigger the ad. The two settled in 2005.

Google lost cases in France, but has won others in the US.
