Today, in the age of mass incarceration, which affects more black people than slavery ever did,white people still create and maintain the unjust laws, they still own the prisons and jails, and they still hold themajority of positions of power to enact their skewed version of justice.
I am not sure that a simple transfer of power from white people to brown/Black people would entirely fix the injustice/corruption issue that exists. This reminds me of Justice Clarence Thomas, who is suspected of taking gifts and donations as forms of payment. Instead, perhaps becoming better involved and informed about our options can improve our chances of having BIPOC in positions of power.
