Mark Twain said: “Write what you know.”  While some writers might disagree, Twain’s words define Dan Carlson’s approach to writing, and have been central to the several books and numerous articles he has authored.  Being a retired police officer and law enforcement educator, there has been no shortage of ideas and information to stimulate sitting down at the keyboard.    Life experience provides a wide range of thoughts to be explored, and this blog will be one more helpful vehicle for sharing and learning.
