The actress has the former 'Price Is Right' host in her corner.
Mia Farrow has been facing some backlash since she tweeted out the address of Dr. Walter Palmer, the man responsible for killing Cecil the Lion. But Bob Barker tells ET that he doesn't see anything wrong with what she did.
The Minnesota dentist has been in hiding ever since it was revealed that he hunted and killed the beloved 12-year-old lion, a favorite at Hwange National Park and a tourist draw that was also being tracked for scientific research by Oxford University.
He also released an apology shortly after his practice become a memorial for the dead feline. "I had no idea that the lion I took was a known, local favorite, was collared and part of a study until the end of the hunt," Palmer wrote in an apology letter to his patients. "I relied on the expertise of my local professional guides to ensure a legal hunt."
Despite his apology, Farrow, like many other celebrities, took to Twitter to share her outrage: "CecilTheLion -- Gentle protector of 6 cubs. Loved by many. Killed by Dentist Walter Palmer."

She also included the dentist's address. The tweet has since been removed.
"@MiaFarrow seriously? Are you hoping for this guy's death," one Twitter user said of her post. "Jail time yes but why are we sending a mob?"
While the 70-year-old actress received numerous negative responses to her tweet, Barker defended Farrow's decision to share the Dr. Palmer's address.
"Well if by publicizing his address they can make him miserable, I say publicize that address," the former Price Is Right host told ET. "Because this man deserves to be made miserable for years to come."

Barker warned that the outrage over Cecil’s killing could have lasting effects. "He is losing patients, and is he married, does he have children?" he asked. "His children are going to have a rough time at school, and I don't envy him one bit. But he deserves all the misery he receives."
The 91-year-old animal activist also shared what he thinks the dentist deserves for what he did. "I would love to see them extradited Dr. Walter Palmer spend a little time in an African jail," he declared. "That would just be a thing of beauty and a joy forever."

Barker, like many other activists, hopes that Cecil the Lion's story will help bring awareness about the worldwide problem of animal poaching.
"The animal rights movement has just made humongous strides. Why? Awareness. That is what it takes, we have to make people aware," he told ET. "They don't realize how much suffering is going on in the animal world. We have to make them aware."

We've already seen what awareness can do thanks to Jimmy Kimmel, who asked his viewers to donate to the Wildlife Conservation Research Unit following Cecil's death. The host's Tuesday segment on Jimmy Kimmel Live helped to raise $150,000 for the organization.
Kimmel was so passionate talking about the lion that he got choked up. See it here:
