Miller, Rory. "Violence: A Writer's Guide." Pacific Northwest. Wyrd Goat Press. 2012.
Review: Again Sgt. Miller has coupled his life experiences in a violent work world into something educational and useful, for a writer as well as a person learning about violence for self-defense. This book, as is his other efforts, is well done. It refreshes about information from his other efforts as well as provide solid clues on how to write about it with authenticity and accuracy.
Example of content: The three essential elements of self-defense he provides in this book are a good primer for anyone seeking self-defense training. Knowing of and about these elements gives a person ammunition to seek out good self-defense training. When you couple this with the information Sgt. Miller provides in this book as well as his other efforts you have a good foundation to separate the chaff from the wheat of self-defense instruction.
What are the thee essentials? Awareness-Initiative-Permission. I could give you my view of this but prefer recommending you read his book as mentioned above. His explanations are far better than mine.
