In a lot of the instances the departments, at the department level, did track injury rates before versus when a taser came in. Obviously they've had injuries in the past . For example, in the United Kingdom, they were documenting injury rates to officers. When a taser was being deployed, there were no injury rates on those particular instances where a taser had been deployed to an officer. However, if an officer had used a baton or gotten into a fist fight, there'd been an injury and the officer had to go to the hospital.
A lot of that data is in worker compensation claims made by the officer and it's held by the cities. But a lot of that data really comes out of the agencies reporting back to us. Unfortunately, anywhere in the world, there's no central reporting of injury rates to officers or suspects, so a lot of that data is used by the local municipalities.
I included a PowerPoint presentation that gets some of that data for your reference. That is taken from public records at the cities and the departments that report those statistics. And it's, by far, not comprehensive for every agency.
