The Federal Bureau of Investigations is updating their system for tracking deaths caused by police officers after facing increasing pressure and criticism over its current standards of reporting this information.

The new system, set to publish some data as early as 2016, will keep a more detailed record of incidents in which police officers kill or seriously injure civilians. Under the new guidelines, the FBI will expand its practices to track incidents involving not just firearms, but also physical force, Tasers and any other weapon, according to The Guardian.

“We are responding to a real human outcry,” said Stephen Morris, assistant director of the FBI’s Criminal Justice Information Services Division, The Washington Post reported. “People want to know what police are doing, and they want to know why they are using force. It always fell to the bottom before. It is now the highest priority.”

The data will also be published in near real-time, according to The Washington Post.

The FBI currently publishes yearly on instances of "justifiable homicide," defined as when a law enforcement officer kills a "felon" in the line of duty. The data published shows the number of incidents in a year and what kind of firearm was used. However, other datasets from The Guardian, The Washington Post, and Fatal Encounters, who have started tracking fatal incidents between police and citizens, show a gap in the FBI's reporting.

While the FBI's data shows there were 444 "justifiable homicides" by police officers in 2014, Fatal Encounters, an independent data initiative, tracked 1,270 deaths at the hands of police in that year. This may a result of different definitions on what should be counted, but is also a sign that there may be underreporting. The FBI data also lacks details such as where the incident occurred, when it occurred and whether or not the person was armed.

It remains to be seen how many law enforcement agencies will comply, as it is not obligatory for departments to submit the data to the FBI. In 2014, only 224 of the 18,000 law enforcement agencies in the U.S. reported this information to the FBI, according to The Guardian.

The FBI's announcement, if carried out systematically, could be an important resource for researchers, police departments and policy makers.

A better system to track the number of killings by police officers has also been a demand of Black Lives Matter protesters.
