Eighteen issues of the LAPD's Daily Training Bulletin (1951-1952) issued by the Field Training Unit of the LAPD early in the tenure of Chief William H. Parker. These bulletins cover a variety of practical topics for use in day-to-day policing, including How to Arrest on a Warrant, How to Make Juvenile Arrests, How to Search a Car, How to Recognize Narcotics Violations, and How to Hand Repossession Disputes. The bulletins were distributed to officers each day at roll call for several years and were eventually compiled into a single book. Of particular interest here are six issues relating to juveniles, which acknowledge increasing societal concern with the problem of "juvenile delinquency," and encourage offers to adopt preventive strategies, rather than merely reacting to crime.
