I see he is following the Trump playbook of pardoning dead black people from a century ago to avoid criticism for their covert racist actions in the present day.
It's still better late than never.
Florida's Governor does not have Pardon Power; that power is in the hands of the Florida Cabinet, which consists of the Governor, the Lt. Governor, the Secy. of Agriculture, the Attorney General, and the Chief Financial Officer. One Governor and Four Wannebe Governors. In the case of the Groveland Four and the case of Pitts and Lee (a similar case), the fraudulent victims and their families were connected with local pols, and legislators (including Democratic legislators over the years) were obstacles to this.
I advocate absolute, permanent, irrevocable, and unreviewable pardon power for FL's governor and for the President. It's the one power that I want concentrated in the hands of one man.
