The Anatomy of Killing) Read Dave Grossman, On Killing, Chapters 1and 2

Read the chapters and answer the question : How does authority contribute to the ability to kill? How does being part of a group contribute?
The answer must be from this reading dont use any other sources and do not site any thing from the text. Dont use any in text citation. I am unable to attach a PDF right now so when you get this message me so i can send the PDF file to you because the reading cant be found online.
