“This is a momentous verdict”, said the High Commissioner for Human Rights, Michelle Bachelet, in a statement.
The white former Minneapolis police officer was convicted on Tuesday of murdering the 46-year-old African American man in May of last year.
Mr. Chauvin was filmed kneeling on Mr. Floyd’s neck for more than nine minutes, sparking mass protests globally against racism.
More needed in battle for justice
Bachelet praised the “courage and perseverance of George Floyd’s family and many others in calling for justice”, but said that for “countless other victims of African descent and their families, in the United States and throughout the world, the fight for justice goes on”.
Ms. Bachelet said the battle for justice in cases of excessive force or killings by police “is far from over”.
She called for “robust measures” to reform police departments across the US, stating that so far, they had been “insufficient to stop people of African descent from being killed”.
Police officers have rarely been convicted – or even charged – for deaths that occur in custody.
The practice of policing in the US and elsewhere must be rethought with a “whole-of-government and whole-of-society” approach to “dismantle systemic racism” she added.
Uprooting systemic racism
The UN human rights chief called for a critical examination surrounding the context of George Floyd’s killing by revisiting the past and probing its “toxic traces in today’s society”, including the legacies of enslavement and transatlantic slave trade and the impact of colonialism, which need to be “decisively uprooted”.
She added that achieving racial justice and equality also requires “the full and equal participation of people of African descent in ways which transform their interactions with police and in all aspects of their lives”.
“If they are not, the verdict in this case will just be a passing moment when the stars aligned for justice, rather than a true turning point”, she warned.
