But we had police shooting at reporters on live TV already. It's not that documented misconduct didn't exist. What's missing is savage consequences for misconduct.
In terms of consequences that is why I believe there should be review at the state or federal level. The only way you can do that review at scale is with body cam footage. Most cases will be open and shut, but just the idea of being recorded AND being scrutinized by a higher authority would make a huge difference in behavior.
