Wildlife agency officials in Florida have been advised to avoid wearing their uniforms after a series of death threats over the shooting of a tiger.
The agency's officials have received hundreds of angry e-mails and calls
An officer from the Fish and Wildlife Conservation Commission killed the tiger last week after it escaped from a home owned by a one-time Tarzan actor.
The agency said Bobo, a 600-pound (270-kg) tiger, had lunged at the officer during the hunt.
It said it had received at least five death threats since the killing.
'Hanging from a tree'
Agency spokesman Willie Puz said the threats included a call from a woman who demanded his hanging.
"She said someone should shoot you for defending the officer and lying to the public [and] that I should be hanging from a tree," Mr Puz was quoted as saying by the Associated Press news agency.
Rodney Barreto, chairman of the FWCC, said earlier that the danger posed by the tiger had been very real:
"Our officer was face to face with a instinct-driven predator that hadn't eaten in at least 26 hours and was on the run."
According to the agency's directive, while armed officers must stay in uniform, other field staff - from fishery experts to scientists - should wear street clothes as a precaution following the public outcry over the killing.
Tiger owner Steven Sipek - who played Tarzan in two films in 1969 and 1972 - has insisted that Bobo was a tame pet posing no threat.
