Section II: law enforcement officers assaulted
Methodology
Section II contains data pertaining to assaults on sworn city, county, and state law enforcement officers. The information is collected monthly from UCR Program participants who compile and submit their data by one of two means: either directly to the FBI or through their state UCR Programs.
Law enforcement agencies report the number of assaults resulting in serious injury or instances where a weapon was used that could have caused serious injury or death. Other assaults are recorded only if they involved more than verbal abuse or minor resistance to an arrest.
The data in Section II are based on information reported to the national UCR Program by 9,688 law enforcement agencies. The contributing agencies provided the national Program with 12 months of officer assault statistics and an annual number of police officers employed. These agencies offered services to over 212 million inhabitants or 74.4 percent of the Nation's total population. Table 2.1 presents the U.S. population by groups and summarizes the population coverage by UCR contributing agencies. Tables 40 through 42 present data by population groups.
Overview
In 2001, a total of 9,688 law enforcement agencies reported that 56,666 law enforcement officers were assaulted in the line of duty. The average of 12.2 assaults per 100 officers in 2001 was 5.4 percent lower than the 2000 rate of 12.9, and 3.9 percent below the 12.7 rate recorded in 1997. The 2001 rate was 31.5 percent lower than the 1992 rate of 17.8 assaults per 100 officers. (Based on Tables 34 and 36.)
By region, the rate of police officers assaulted was the highest in the South, the most populous region, at 13.6 assaults for every 100 officers. Law enforcement agencies in the Northeast reported a rate of 12.7 assaults per 100 officers, the West had a rate of 10.9, and the Midwest a rate of 10.1. (See Table 34.)
Among the population groups, the highest rate of assaults, 17.9 per 100 officers, occurred with law enforcement officers serving cities with populations over 250,000. Of all cities, those with under 10,000 inhabitants reported the lowest rate, 7.4 assaults per 100 officers. Law enforcement officers in suburban counties experienced an assault rate of 10.1 and rural counties a rate of 5.3 per 100 officers. (See Table 41.)
Injuries
Nearly 29 percent of all law enforcement officers assaulted suffered personal injuries in 2001. The rate of 3.5 injuries per 100 officers was slightly lower than the rate of 3.6 per 100 officers in 2000.
Among the Nation's four regions, the Northeast reported the highest rate of officers injured during assaults at 3.8 per 100 officers. The South reported a rate of 3.7 per 100 officers, the Midwest a rate of 3.2, and West a rate of 3.1. (See Table 34.)
Law enforcement agencies in cities with populations ranging from 100,000 to 249,999 reported the highest assault injury rate of 5.2 per 100 officers. Agencies in cities with less than 10,000 inhabitants reported an injury rate of 2.4 per 100 officers. Agencies representing suburban counties reported an injury rate of 2.9 per 100 officers, and rural counties reported the lowest rate among population groups, 1.8 per 100 officers. (See Table 41.)
Weapons
Just over 80 percent (80.2) of assaults on law enforcement officers in 2001 were most often committed with personal weapons such as hands, fits, feet, etc. Of those officers assaulted with personal weapons, 30.0 percent suffered injuries. Firearms accounted for 3.2 percent of all assaults on police officers. When offenders used firearms, 11.6 percent of those officers assaulted suffered injuries. Knives and cutting instruments were used in 2.1 percent of assaults and resulted in injuries to officers in 17.6 percent of those cases. Other dangerous weapons, which accounted for 14.5 percent of all assaults on officers, resulted in personal injuries to 26.3 percent of these officers. (See Table 36.)
Circumstances
In 2001, the majority of officers assaulted (31.4 percent) were responding to disturbance calls, which include family quarrels, bar fights, person with firearm, etc. Thirteen percent of the officers were assaulted while maintaining custody of prisoners, and 11.2 percent were assaulted during traffic pursuits or stops. Officers investigating suspicious persons or circumstances accounted for 10.3 percent of the assaults, and officers assaulted by mentally deranged assailants accounted for 1.6 percent. Officers assaulted while pursuing burglary suspects or investigating burglaries in progress accounted for 1.4 percent of assaults on officers. One percent of officers were assaulted during robbery circumstances, and one percent were assaulted during civil disorders (such as mass disobedience or riots). Less than one percent (0.3) of the officers were assaulted in ambush situations. Slightly over 16 percent (16.1) of the officers assaulted were attempting other arrests. The remaining 12.7 percent of officers were performing other duties at the times of their assaults. (See Table 38.)
Types of Assignment
Of those officers assaulted in 2001, 80.3 percent were assigned to vehicle patrols (20.7 percent of those officers were assigned to 2-officer patrols, and 59.6 percent were assigned to 1-officer patrols). Of the total number of officers assaulted, 5.4 percent were on detective or special assignment, and 14.3 percent were performing other duties. Fellow officers were at the scene assisting 71.4 percent of the assaulted officers. (Based on Table 38.)
Times
Most assaults on law enforcement officers in 2001 (15.5 percent) occurred between the hours of midnight and 2 a.m. Similarly, over the last 10 years (1992-2001), the majority of assaults on law enforcement officers (30.8 percent) occurred between 10 p.m. and 2 a.m. (Based on Table 37.)
Clearances
Of the total number of assaults on law enforcement officers in 2001, 89.3 percent were cleared by arrest or exceptional means. By circumstance, 92.5 percent of assaults on law enforcement officers that occurred during disturbance calls (family quarrels, bar fights, person with firearm, etc.) were cleared by arrest or exceptional means. Officers assaulted in ambush situations was the circumstance with the lowest percent of clearances, 71.5 percent. (See Table 40.)
