“No matter what the grand jury does, let us remember that true justice will come only when our criminal injustice system is radically transformed: when we no longer have militarized police forces, wars on our communities, a school-to-prison pipeline, and police departments that shoot first and ask questions later. True justice will be rendered not when when a single “guilty” verdict is rendered in one man’s case, but when the system as a whole has been found guilty and we, as a nation, have committed ourselves to repairing, as best we can, the immeasurable harm that has been done.”
