It was the bounty hunter who calls himself "Dog" -- because it's God spelled backward -- who finally tracked down convicted rapist Andrew Luster in Puerto Vallarta on Wednesday.

And what did Ventura County Sheriff Bob Brooks, officials with the Federal Bureau of Investigation, and Patricia Murphy from the Ventura County District Attorney's Office say about the bounty hunter's efforts at a joint press conference later in the afternoon?

Thanks, but no thanks.

"I think his actions are just beyond the bounds I can condone," said Ralph Boelter, assistant special agent in charge of the Los Angeles office of the FBI. "It is certainly something we don't endorse."

Duane Chapman -- the man who identifies himself as Dog -- is being hailed by some as the reason Luster now faces possible extradition from Mexico to begin serving his 124-year prison sentence.

Luster, 39, was convicted earlier this year after prosecutors proved he took three women to his home from 1996 to 2000 and videotaped himself raping two of them after giving them the so-called date-rape drug GHB. He was tried in absentia after Luster fled in January.

Few in the world of bail-enforcement agents -- those charged with finding people who skip bail -- endorsed Chapman's actions.

Tony Luna, a bail bondsman in Ventura, said he wouldn't use a bounty hunter like Chapman. Penny Harding, president of the California Bail Agents Association, said being a bounty hunter requires "specific training."

And count Bob Kimsey, a bond-enforcement agent based in Las Vegas, among the unimpressed as well.

"He's one of the most unprofessional bounty hunters we've ever seen," Kimsey said. "A professional has no image in the media. Dog tries to make news any way he can and portrays himself as one of the best bounty hunters, but he just causes more problems. We wish he would go away."

Several calls to Chapman's office in Hawaii to speak with his associates were not returned.

Kimsey, whose firm, Kimsey and Associates, employs about 20 agents and has a revolving caseload of 500 skipped bonds at any given time, said those in the industry have spent years trying to kill the image of the rough-and-tumble bounty hunter.

In fact, they've been trying to move away from the term bounty hunter. Chapman, however, embraces the image -- muscles, tight black shirts, mullet haircut and "Dogisms" like this posted on his Web site: "Born on a mountain, raised in a cave. Arresting fugitives is all I crave."

Definitely not the image Kimsey likes to see.

"Bounty hunter is the old guy or renegade who took a three-minute class on the Internet," Kimsey said. "Most of us are professionals who have been law enforcement officers."

According to Bob Burton, author of several books on bail-enforcement agents, the job of a bounty hunter is quietly crafted in the shadows and is decidedly less glamorous than Chapman would have people believe.

Burton, director of training at the National Institute of Bail Enforcement, said that to become one of the more than 2,200 agents that pass through his course, "You'd better show up wearing a suit."

He said being an agent requires a higher level of sophistication now because laws -- state, federal and even international -- change regularly and are more complex than ever before.

Burton said it was obvious Chapman wasn't clear on what his legal limitations were in Mexico. If he were, Burton said, he wouldn't be sitting in a Mexican prison.

"Dog's results are fine, but if you do it professionally, you would have found the man, shown the warrant to the Mexican authorities and let them do the arrest," he said. "Dog had zero arrest authority in Mexico. Yes, he's making some people happy, particularly the victims, but he clouds the issue."

Chapman's reasons for going after Luster are also somewhat murky.

Under Luster's bond agreement of $1 million, that money eventually will be released back to the Max Factor heir's family, because they posted the full amount in cash.

Which means, according to Brooks, it's not likely Chapman will ever see any money.

Mark Bernstein, a Fresno attorney who specializes in bail, said normally when a bondsman posts the bail -- 10 percent of the court-ordered amount -- and the person skips out, he will hire bounty hunters to track them down because the bondsman is on the hook for the full amount.

But, Bernstein said, if the bond is cash and the person is independently rich, the incentive to stick around for a trial isn't quite there.

"Who is going to pay to look for the fugitive? Nobody, because he paid for the bond himself," Bernstein said. "It's a small loophole that favors wealthy clients."

Bernstein said he didn't see a way for Chapman to collect any money related to the bond.

Brooks said, however, he could be in line for $10,000 in reward money posted by the Ventura County Sheriff's Department and the FBI. He said the couple who spotted Luster in Puerto Vallarta also could make a claim for the reward.

The sheriff said that even if Chapman got the $10,000, it wouldn't likely cover the costs incurred for going after Luster.

Brooks, Kimsey and Burton said they believe a book or a movie deal is what Chapman is really after.
