“ubstitute terminology such as ‘person who committed a crime’ and ‘individual who was incarcerated’ in speeches and other communications”
How ‘bout ‘incarcerated’ or ‘Citizen’? We have no need of anything further. Prison was for paying their debt (some, at the end of a rope). Citizens have Rights and Liberty; no caste system.
One is Free or one is behind bars, there is no gradation.
