Study Overview

Our analysis of FBI data reveals that 11.9% of police officers – nearly one in eight – were victims of assault while on duty in 2020. A total of 60,105 officers were reported assault victims, many with guns, knives and other weapons. 

Each year, the FBI releases Law Enforcement Officers Killed and Assaulted (LEOKA) data. 2020 is the most recent year of state level data available. Not every law enforcement agency reports assault data to the FBI, so nine states with limited statistical representation are excluded from our report. The data includes duly sworn federal, state, city, county, university, college and tribal law enforcement officers. 

The table below shows the total number and percentage of law enforcement officers in each state who were assaulted on the job in 2020.

2020 Law Enforcement Officers Assaulted by State

A total of 505,212 officers were included in the FBI data, or 72.5% of all police officers in the U.S. in 2020. The officers included in the data were taken from 9,895 different law enforcement agencies and serve more than 235.5 million people, or 71.5% of the population.  

Prominent national events and the COVID-19 pandemic brought additional stressors to many law enforcement officers.

According to the American Journal of Criminal Justice, “Racial tension towards police escalated during the pandemic due to the deaths of Breonna Taylor and George Floyd at the hands of officers in Kentucky and Minnesota, respectively. Urban centers drew crowds protesting, rioting, and looting; officers in large agencies became both the focus of acrimony and responsible for ensuring unruly crowds’ safety from a viral threat.”

In 2020, “law enforcement was responsible for both providing a presence to deter violent and unruly behavior, but also to encourage social distancing and use of face masks and other protective wear – an unprecedented dual responsibility.” – Stogner J, et al. American Journal of Criminal Justice.1
