I found this book very interesting. It covers what types of questions people ask when interviewing people wheather they be suspects in a crime or a job applicant. It is mostly based on crime victims or crime perpetrators, but the same principle applies when asking any question. Many topics are covered and for the Police Officer it contains up to date information on current situations which occur in interview rooms, ie. bad questioning. It is well written and very well researched by the respectable authors. Dont ask "Should i buy it?", instead ask, "When will I buy it?"
