New NIJ Journal Article Focuses on Conducted Energy Device Policies

Better knowledge of the use and effects of Conducted Energy Devices (CEDs) and developments in constitutional law have prompted law enforcement in the past decade to revisit policies on the widely used “less-lethal weapon” which stuns and usually immobilizes subjects to make it easier for law enforcement officers to subdue them.

Since CEDs were introduced as a law enforcement tool, the NIJ has sponsored research related to implementation, officer training and potential effects. NIJ-sponsored research on CED effects has repeatedly stated that the effects of electrical shock from these devices are complex and more research is needed to fully understand them.
