Sgt. Charles Black is a 35 year veteran of the Iowa State Patrol during those years he has had many experiences and he shares his favorites in this book. In 35 years I have seen a lot of changes from the name of the organization to the primary function. From hearses to ambulances to rescue units with EMT's. From paper list of stolen cars to computers.From no recorders to body cameras. From fist fights to gun fights.But human nature and the effects of drugs and alcohol remain the same.
