Summary of John E. Douglas & Mark Olshaker's Mindhunter

Please note: This is a companion version & not the original book. Sample Book Insights: #1 The FBI's Investigative Support Unit attempts to develop a profile of the criminal mind, by analyzing the clues at a crime scene. Everything tells us something about the unknown subject who committed the crime, and we can make various conclusions when we see patterns start to emerge. #2 When interviewing prison ers, we try to know as much about them as possible before the interview.
This is to make sure they aren't playing self-serving or self-amusing games with us. #3 When interviewing killers, you should always try to figure out what made them kill certain victims. The old cliché about killers visiting the graves of their victims is often true, but not always for the reasons we originally thought. #4 The changing nature of violent crime is another reason we need to understand it.
Serial killers and rapists are the most difficult to catch, because they are motivated by more complex factors than the basic ones I've listed.
