Question

As an expert in computer security, you have been approached by an organisation that campaigns for the rights of torture victims and have been asked to help the organisation gain unauthorised access to the computer systems of an American company. This will help them confirm or deny that this company is selling equipment that is used directly in the torture of political prisoners. Discuss the ethical dilemmas that this request raises and how you would react to this request.
