Letters in the media urged capital punishment for rapists

Letters in the media urged capital punishment for rapists. One letter writer proposed that a rapist be exiled to his true habitat, the jungle, because the writer believed the rapist adhered to the law of the jungle. In answer to this, a newspaper replied the problem is that capital punishment or a sentence such as ordering the culprit to live in his "habitat" will certainly be opposed by human rights groups. Moreover the threat of capital punishment in countries such as the US has failed to deter rapists. Apparently [according to the newspaper] the only way to permanently stop rapists is to castrate them. It can be used as a legal threat, i.e. passed into law or implemented tacitly without knowledge of the public or even the rapists themselves.
