Thanks for keeping politics out of non-political literature. If anyone here wants to discuss the matter, there are plenty of more appropriate places to do so, like Reddit or Facebook.
Here's my 2 cents, for what it's worth. This will be my only post in this thread.
Creating political change is like creating a diamond: you need to keep up pressure over time. When an officer kills someone, we get pressure for a short time, but it's not enough to effect any real change.
Police killings like this have occurred at least twice a year for as long as I can remember, and the response is always the same. Democrats say they'll pass new laws. American corporations make nominal donations to some charity or other and tweet something inspirational. The Fairweather Protesters get out their pitchforks and cameras so they can post everything to Instagram. A couple of weeks later, the protests are just a blip in a Facebook timeline, leaving those who are truly dedicated to stopping police brutality to tread water until the next time an officer murders someone.
For those who advocate change, what were you doing two weeks ago, and what will you be doing two weeks from now? If you want change, stick to that advocacy. Don't just donate a few dollars and pay lip service for a week or two every time a black man is murdered by law enforcement.
Defunding law enforcement without having anything to replace it is a recipe for disaster. If you want change, figure out what you want to change and how. Carrying signs and chanting slogans is great, but without a coherent plan for reform, you'd be equally served by screaming into a void.
