LEOKA—Officers Assaulted (by Type of Activity)

Line 15, Time of Assaults

Search the database for records with the following data elements and all specified data values:

Data Element 1 (ORI Number)—all incidents with the same ORI number except when Data Element 25C (Other Jurisdiction, Officer) is reported so that all victim officers will be counted by their employing agencies only.

Data Element 3 (Incident Date/Hour)—month and year of each incident report for identical ORIs.  Use the month and year of the incident date or, when the incident date is unknown, the report date (entry of a date with an indicator of R) to tally the number of law enforcement officers assaulted.

Data Element 24 (Victim Connected to UCR Offense Code[s])—offense codes 13A and 13B.

Data Element 25 (Type of Victim)—entry of L = Law enforcement officer.

Data Element 23 (Victim [Sequence] Number)—if more than one Victim Segment is provided within an incident, count each (L) victim, entry of 002-999.

Note:  The time frames for summary reporting begin at one minute past the hour (:01) whereas the time frames for NIBRS reporting begin on the hour (:00).

To convert NIBRS data to Summary data and place all data about officer assaults in the appropriate time frames for Time of Assault (extracted from Data Element 3 Incident Date/Hour), the FBI uses the following conversion guidelines:

AM     
12:01-02:00     Data Element 3 (Incident Date/Hour)—entry of 00-01
02:01-04:00     Data Element 3 (Incident Date/Hour)—entry of 02-03
04:01-06:00     Data Element 3 (Incident Date/Hour)—entry of 04-05
06:01-08:00     Data Element 3 (Incident Date/Hour)—entry of 06-07
08:01-10:00     Data Element 3 (Incident Date/Hour)—entry of 08-09
10:01-12:00     Data Element 3 (Incident Date/Hour)—entry of 10-11

PM     
12:01-02:00     Data Element 3 (Incident Date/Hour)—entry of 12-13
02:01-04:00     Data Element 3 (Incident Date/Hour)—entry of 14-15
04:01-06:00     Data Element 3 (Incident Date/Hour)—entry of 16-17
06:01-08:00     Data Element 3 (Incident Date/Hour)—entry of 18-19
08:01-10:00     Data Element 3 (Incident Date/Hour)—entry of 20-21
10:01-Midnight Data Element 3 (Incident Date/Hour)—entry of 22-23

Two examples follow:

If the incident occurred on or between midnight and 0059 and the agency reported 00 for the Hour in Data Element 3 via NIBRS, the FBI converts the time to the summary time frame of 12:01-2:00 a.m. for the Time of Assault.

If the incident occurred on or between 2300 and 2359 and the agency reported 23 for the Hour in Data Element 3 via NIBRS, the FBI converts the time to the summary time frame of 10:01-12:00 p.m. for the Time of Assault.

For those incidents in which an agency reports Data Element 25A (Type of Activity [Officer]/Circumstance) and either the Incident Date of Data Element 3 is unknown (entry is R) or the Incident Hour of Data Element 3 is unknown (entry is blank), the FBI has programmed its system to designate the time frame for the Time of Assault in order to capture the officer assault.  The time frame is derived using the same percent distributions calculated for the 10-year table "Law Enforcement Officers Assaulted, Time of Day, Percent Distribution" in the most current edition of the annual publication Law Enforcement Officers Killed and Assaulted.  The computer will select a time frame for the incident based on a monthly rotation of the data (entry of R or blank) in accordance with the most current published percent distributions.  Each year the FBI will update the system to use the most updated percent distributions.
