Nate Allen, Knoxville's Deputy Chief of Police, was invited to discuss 400 Things Cops Know: Street-Smart Lessons from a Veteran Patrolman by Adam Plantinga. Allen remarked "This book is a great way to build understanding and transparency between the community and police officers. It is extremely important for the community to know and understand the laws provided for police officers to perform their job in a safe and responsible manner." He responded to many questions from the audience, but the recording captured only his remarks. This recording is edited from his answers to those questions.
