Each month the Rialto Police Department submits a Uniform Crime Report (UCR) to the Federal Bureau of Investigation (FBI) containing an array of crime related statistics for the municipal boundaries of Rialto.  One of the main purposes of this report is to capture the number of Part I offenses reported by citizens.  The FBI, in turn, uses this data to identify fluctuations in crime; these comparative studies are performed on agencies throughout the United States that submit data.  Although there are hundreds of crime types that are reported by citizens, a committee established in the 1920s by the International Association of Chiefs of Police (IACP) decided to select a small number of crimes to be used as a focus for UCR reporting purposes which are today known as the Part I offenses or Index Crimes (see FBI definitions of these categories at the bottom of this page).  It was agreed upon by the committee that the offenses selected for UCR were representative of "crimes most likely to be reported and most likely to occur with sufficient frequency to provide an adequate basis for comparison".  The following table reflects the Part I crime totals reported by the Rialto Police Department annually to the FBI:



Criminal Homicide — (a) murder or non-negligent manslaughter defined as the willful (non-negligent) killing of one human being by another; or (b) manslaughter by negligence defined as the killing of another person through gross negligence

Aggravated Assault — an unlawful attack by one person upon another for the purpose of inflicting severe or aggravated bodily injury; force is usually accompanied by the use of a weapon or by means likely to produce death or great bodily harm

Burglary (breaking or entering) — the unlawful entry of a structure to commit a felony or a theft; attempts are included
