PETA called for Palmer to be charged, tried and if found guilty “preferably hanged.”

Here is the official statement from PETA co-founder and President Ingrid Newkirk:

Hunting is a coward’s pastime. If, as has been reported, this dentist and his guides lured Cecil out of the park with food so as to shoot him on private property, because shooting him in the park would have been illegal, he needs to be extradited, charged, and, preferably, hanged. To get a thrill at the cost of a life, this man gunned down a beloved lion, Cecil with a high-powered weapon. All wild animals are beloved by their own mates and infants, but to hunters like this overblown, over-privileged little man, who lack empathy, understanding, and respect for living creatures, they are merely targets to kill, decapitate, and hang up on a wall as a trophy. The photograph of this dentist, smiling over the corpse of another animal, who, like Cecil, wanted only to be left in peace, will disgust every caring soul in the world.

The statement isn’t out of character for the organization, which has earned a reputation as the one of the most radical defenders of animal rights.
