"I'm a hunter," Knowlton told WFAA. "I want to experience a black rhino. I want to be intimately involved with a black rhino. If I go over there and shoot it or not shoot it, it's beyond the point."
Although Knowlton bid anonymously, his name was posted on Facebook shortly after the auction. Then the death threats began.
"They're wanting to kill me," he said (this time about himself). "They're wanting to kill my children. They're wanting to skin us alive."
Knowlton claims he's had to hire round-the-clock private security, which surprisingly, was not built into the cost of the license. He also told WFAA that local law enforcement and the FBI have been looking into the threats.
