Uh... what they could do to help officers improve most might be shipping a device that doesn't seem to mysteriously malfunction or be turned off during the most controversial use of force incidents.
The way bodycams are supposed to help is by forcing officers to be accountable for their actions. When police have plausible deniability due to poorly designed tech, all these expensive devices become basically worthless.
In my cynical moments I have wondered if making such bad tech is actually a selling point for Axon and its competitors. They're selling to police departments; the less likelihood bodycams have of embarrassing police, the more likely they are to make a sale. Check the box, move along. I try to have more faith in our institutions, but the abject failure of bodycams from a technology perspective makes me wonder.
I supposed it could also just be due to a few companies having a lock on an enterprise hardware market.
