I think people want to protest the idea of justice reform.

This time, in this one instance, it seems like the justice system is working. But there have been reports of many people being abused by the people and system they rely upon. Police departments using body cameras is still a fairly new concept. Until not so long ago, it was only through 3rd party smartphone videos that the public could even prove these things happen.

There is nothing wrong with wanting better for society in general, especially when addressing how our justice system and law enforcement fit in that society.
