Query: Very Necessary

Don Rabon's credentials speak for themselves. He is a very long term trainer in interviewing with an emphasis upon discourse analysis in legally sound interviewing. His works (including "Investigative Discourse Analysis") are not a "Cliff Notes" or "MTV video" of interviewing which appears to be desired by our society, rather they are thoughtful and careful works, like pieces of a puzzle, where study and practice are needed to embrace the techniques.There is no "quick fix" to the art of interviewing and it is not something for the unlearned, but if your profession calls for interviewing skills, and you have a basic foundation of grammar, you will love this book. It is to be read slowly and carefully. I marked up mine.It saddens me to read of police officers who did not "stay the course" and learn the material.Those who are our country's best in Statement Analysis, are those who practice their craft, forever learning and forever growing in their understanding of interviewing.
