A little detail on the work to get the book done

Lee Harris did an awesome job with tech editing, keeping me on track. Every beta reader provided critical feedback, with most commenting that they were taking my advice and giving it right back to me (as in, they were telling me straight up what they liked and did not like so that the book could be the best it could be).

I reflected on my current and past careers in law enforcement, digital forensics, ediscovery, and all training and education received in the past three decades to put into something manageable. The intent of the book is to get you thinking objectively to see your cases more accurately. 

I also wanted to write it in a manner that you can digest it in a weekend or a night if you are a fast reader. This is not a textbook or written so highly technical that you need a lot of time to comprehend it. I wanted it to be useful before you finished the first chapter, and before you finished the second, and the third, and through the appendix. 



As of today (Saturday, April 6, 2024), on Amazon, the book sits at:

#1 in Law Enforcement

#1 in Computer Security & Encryption

#3 in Criminal Procedure Law

#5 in Law Enforcement Politics

Beta readers

It was a difficult thing to ask for beta readers because (1) I respect the opinion of each of them, (2) I asked for critical feedback that would certainly bite a little, and (3) of course being a little afraid of showcasing my spelling and grammar errors in a rough draft....

I cannot thank them enough, and I promised each of them a copy of the book in exchange for their opinion, whether they liked the book or not.

Nicole Beckwith, Graham Horsman (foreword), Jason Jordaan, Heather Charpentier, Harlan Carvey, Kevin, Ripa, Dave Stenhouse, Lee Harris (Tech Editor), Chad Gish (foreword), Derek Eiri, Michael McGowan, Patrick Siewert, David Neal, DFIR Diva, Lorie Hermesdorf, and Jessica Hyde.  A few remain unnamed because of their current job and could not publicly comment, but I took their suggestions to heart like all the others.

Do you need this book?

You need this book only if you want to be the best in your casework. If you don't think it is important or that you know enough already, then I advise against getting it. You are fine where you are if you are happy with where you are.

This book is certainly for anyone wanting an edge, to see how to actually "think DFIR" and how to be the best at casework. If you want an edge over competitors, peers, opposing experts, and the adversary, you might want to grab a copy.

In my opinion, if you are at the top of your game, this book will put you in the top 1% of the 1%. If you are just starting out, you will have a huge jumpstart over everyone else who learned this over years of experience. The amount of improvement is up to you because I lay out all you need to do to get where you want to be.

Electronic versions

The only electronic version that will be available is a PDF to those enrolled in the DFIR Investigative Mindset course, which begins online in May 2024 as both a live course and OnDemand course (attendees get access to both versions).

There is no Kindle, no Mobi, and no PDF available elsewhere.
