Have you tried either or are you assuming?
At the federal level, there are a few bills being introduced to deal with qualified immunity or other aspects that need addressing. These may not go anywhere, but more pressure may have an effect on that. Also, hopefully next time there's a massive economic downturn, officials remember that not supporting individuals makes the whole nation a powder keg, ready to spawn riots in all 50 states.
There's also historic precedent that protesting has a lasting change.
It always seems hopeless though when my prejudiced neighbors think the protestors are wrong and should be shot. These prejudiced people can be police, lawyers, and judges. Even outside the justice system they clearly perpetuate systemic issues.
