Of course there is something you can do about. Kill cops and or get them fired. What made you think there wasnt anything you could do?
Which of those have you done?
Thats considered need to know information.
So nothing, then. You're conceding my point. You don't have to be able to remove something in order to express an opinion about it.
Actually I just disproved your point. You claimed there was nothing I could do about it and I proved you wrong....again.
You proved my point, which is that you don't have to be able to do anything about something to express an opinion about it. Now, as for police brutality, what exactly have you accomplished (beyond the glaringly obvious nothing that you've actually done, that is) if you've killed a cop? You've turned him into a martyr, turned the entire police force against you, and put yourself away for a very long time, if not a short stay followed by the termination of your life. At the end of it all, you've created a heroic officer cut down in the line of duty by a violent thug, your family is shamed, and you are either dead or out of sight and out of mind. Wow, way to end police brutality.
