Written by cops for cops, it is designed to address the needs of the agency, the rights of the employee, and the concerns of the public, and give law enforcement the policies and tools to properly investigate and document this high profile area.”

Lt. Craig Dodd of the Fort Collins Police Department states that his agency practices many of the philosophies and protocols developed by Hatch over the years.
