From the NYT article

Representation in the halls of power has clearly worked for some, but we must talk about those it hasn’t worked for. We have not seen, in decades, protests with the scale or scope of those that were unleashed by the killing of George Floyd. New, young, black leaders with the Movement for Black Lives are now emerging, leaders unencumbered by past failures and buoyed by their connection to the ruckus in the streets

From the M4BL website

M4BL demands an end to the wars against Black people. We demand repair for the harms that have been done to Black communities, in the form of reparations and targeted long- term investments. We demand economic justice. We demand defunding and dismantling of the systems and institutions that criminalize, control, and cage us. We demand divestment from ideologies, laws, policies, and practices that harm us, and investment in our communities and movements. We demand political power and community control over the institutions that govern our lives.

We demand nothing short of liberation.
