The body cameras that seem to make a difference are the ones we all carry in our pockets/purses. Axon cameras are nothing special, and the company is not neutral.
That's a very good point. Redactions and denial of public records requests make the Axon cameras mostly useless for bringing police misconduct to light. They might help once a case has become notorious. But they rarely start the process of accountability.
Axon makes drones and tasers and all sorts of other stuff too. Body cameras that are not publicly available at the time of recording are useless theater.
