Editor's note: USA TODAY has removed data on officers from Alaska because state officials discovered errors within the public records they provided.
Every year, tens of thousands of police officers are investigated for serious misconduct — assaulting citizens, driving drunk, planting evidence and lying among other misdeeds.
The vast majority get little notice. And there is no public database of disciplined police officers.
To create the first, journalists at USA TODAY and its affiliated newspapers across the country – and media partners including the Invisible Institute in Chicago – gathered records from thousands of state agencies, prosecutors and local police departments.
Starting with lists of officers who lost their law enforcement certification in 44 states, we are making those records available here.
Search our database of decertified police officers
Search a list of more than 30,000 officers who have been decertified, essentially banned from the profession, in 44 states. Search our exclusive database by officer, department or state.
Help us investigate
This project is a broad collaborative effort of journalists across the country. You can help.
Are you a journalist, a police or government official or a resident who has acquired police discipline or accountability records in your state or city? We want to see those.
We also want to hear from people with information about the conduct of a law enforcement officer or agency that you believe we should investigate.
If you submit public records, our nationwide network of journalists will first work to validate the records' authenticity and work to add them here.
Share your stories of police misconduct with us
We want to hear from you if you believe you’ve encountered misconduct by a law enforcement officer or agency. You can send tips and records about an officer or agency to email@example.com.
Contributors to this project
More than 100 newsrooms across the country contributed to the gathering of public records for this project, led by USA TODAY and its 100-plus affiliated local newsrooms across the United States.
Also contributing substantially to the ongoing records-gathering and release is the Invisible Institute, a nonprofit journalism organization in Chicago that focuses on delving into issues around policing tactics and criminal justice.
If you are a journalist who wants to contribute records to this project or join us in requesting public records from police agencies across the country, please reach out to John Kelly at firstname.lastname@example.org.
