As I have said, and wrote, everything important in life is personal.
Justice is personal. There are two forms of justice. Proportional, or distributive, justice is the notion of receiving what one deserves or what one is worth. Think of equal pay for equal work. Absolute justice, or corrective justice, holds that an injustice against someone is an injustice, regardless of the victim.
George Floyd and his family received some measure of justice today. What Derek Chauvin did to George Floyd was a severe injustice and today it was publicly recognized as such. Many people will try to put this into a larger context and try to make some inference about what this means for society, but at the bottom of it, Derek Chauvin was held publicly and personally accountable for the death of George Floyd.
Justice was served.
That has not always been the case.
