(Social Studies) - Human Rights Assessment - Introduction

We will conduct a Social Inquiry on the Human Rights issue of Inhuman treatment and torture (Article 5 of the Universal Human Rights Bill) . Our case study will focus on the country of Afghanistan.Introduction: The Human Rights issue that we will be researching is “Inhuman treatment and torture.” The reason why we have chosen this topic is because we have prior information about this topic and we feel strongly that it is something that shouldn’t happen and is an important issue that needs to be stopped. There are numerous people within the Middle-East, in Afghanistan that have been subjected to torture or to cruel inhuman or degrading treatment or punishment. Within the research that has been done, we’ve found that there has been Afghan Police Officers killed in a Taliban attack, in Afghanistan, Gardez.
