Equipping police with body cameras may be an effective way to improve the behavior of officers and the public with which they interact, a new study finds.
The study also showed significant reductions in the number of civilian injuries by officers wearing body cameras, and of injuries to the officers themselves.
Officers who didn’t wear body cameras in the study also used force fewer times over the year, though the drop-off was less substantial.
The study comes amid a nationwide effort to outfit more police forces with body cameras following high-profile police killings and instances of misconduct, which have spurred calls for improved transparency and accountability. Body cameras have emerged as a rare point of agreement between reform advocates and law enforcement officials
Many officers reported that the equipment changed citizen behavior and helped to de-escalate confrontations between civilians and police. They also said body cameras improved evidence collection, and helped them more accurately recollect events and fill out reports. According to Jennings, most officers didn’t feel burdened by the body camera.
