A dashboard that summarizes the data on the site shows most of the incidents took place in a street or at a residence and involved potential mental health or domestic disturbances. The most common type of force applied, according to the site, was the use of a takedown.
The site also shows “subject actions that led to use of force,” and indicates that resisting arrest was the top reason for officers’ use of force, followed by “threats” and then “attacks.”
The data also breaks down police use of force on people by their race. It shows that of the 3,677 subjects listed in the database, 44% were Black, while 28% were white. About 18% were Hispanic.
The data also show that in the vast majority of cases officers were not injured, and those arrested were injured at only a slightly greater rate.
Grewal has overseen an expansion of what he categorizes as police accountability measures.
In December, he announced revised statewide rules governing the police use of force, the first update in 20 years. Among the changes was the prohibition of all forms of physical force against civilians except as a last resort, and only once an officer tries to de-escalate a situation.
