Use the system to do what? To convince white people that there is a systemic policing problem in this country that is biased toward black and brown people when every other word from so many white people is that there isn't a problem?
And THAT is the perfect exemplification of what I wrote. Why do you need to "convince white people"? Isn't that the basic problem here: the dependency on the old, rich, white people to "take care of us"?
Use the system to change the laws. How hard is that to understand? If you can't get your congressperson to introduce state and/or federal laws that will change the system, then get into politics, get yourself elected, and make it happen yourself. Get into the police department, work hard to be a leader, and change the institution from within.
You're telling us there's a problem; I'm offering solutions. Kneeling during the national anthem is an attempt to tell us there's a problem; what has Colin done to provide a solution? Said that he'd donate a million dollars to a charity? Has he done it? And how is that going to solve the problem?
"Hippies" during the 60's harped about raising social consciousness; where are they now? (answer: in corporate board rooms, sitting at their $10,000 desk in their multi-million dollar law firm, etc., etc.) Quit telling us there's a problem, and let's actually
do something about it.
