About the San Francisco Police Department

In his inaugural address in August 1849, John Geary, the first elected alcalde (mayor/judge) in Gold Rush San Francisco, reminded the newly elected council that the town was "without a single policeman…. [or] the means of confining a prisoner for an hour."


On August 13 the council selected Malachi Fallon as San Francisco's first Captain (Chief) of Police. Fallon in turn appointed a deputy captain, three sergeants and 30 officers to comprise the first regular municipal police department in American San Francisco.


Today, the San Francisco Police Department is a large metropolitan police department which is organized into four bureaus: Administration, Field Operations, Investigations and Airport.


The Administration Bureau provides support for the other bureaus of the San Francisco Police Department and is frequently the liaison with other city agencies as well as the Board of Supervisors.  The Administration Bureau of the San Francisco Police Department has a number of units and divisions: Behavioral Science Unit, Staff Services Division, Fiscal Division, Support Services Division, Planning Division, Technology Division, Risk Management, and the Training and Education Division.


The Field Operations Bureau contains the Headquarters, fugitive Recovery Enforcement Team, Metro Division, Golden Gate Division, Homeland Security Unit, Community Oriented Policing and Problem Solving and Traffic Company.  The Investigative Bureau is organized into five divisions by crime or specialty: Forensic Services, Property Crimes, Personal Crimes, Juvenile and Family Services and Narcotics and Vice.

According to the book description of First Unit Responder: A Guide for Physical Evidence Collection for Patrol Officers, “Physical evidence cannot be wrong; it cannot perjure itself; it cannot be wholly absent. Only its interpretation can err. Only human failure to find it, study and understand it, can diminish its value." -Presiding Judge, Harris v U.S., 331 U.S. 145 (1947) HOW TO MAINTAIN THE INTEGRITY OF THE CRIME SCENE WHILE CONDUCTING AN INVESTIGATION.  First Unit Responder: A Guide to Physical Evidence Collection for Patrol Officers is a training guide and reference for patrol officers and criminal investigators, who conduct preliminary investigations of crime scenes, to aid in identification, collection, and booking of physical evidence. Written by a veteran of 24 years of law enforcement, the book stresses the importance of understanding the critical nature of physical evidence and preservation of the crime scene as part of the case against a criminal defendant. This book is an important tool for police academies that train recruits and veteran patrol officers, as well as for students of criminal justice who seek guidelines for proper collection and handling of physical evidence”


According to Corporal Andreas K. Mendel, NCO in Charge, Forensic Identification Section, West Vancouver Police, in Canadian Society of Forensic Science Journal, “Mark Hawthorne's easy writing style and use of personal anecdotes make this book a relaxed read. First Unit Responder is a good resource for recruit training or criminal justice/criminology students, or as review material for seasoned investigators.”
