Which factor is critical in maintaining fair treatment of inmates?

Impartiality is fundamental in ensuring that all inmates receive fair treatment within the correctional system. When officers act without bias, they uphold the principles of justice and equality, treating each individual with dignity regardless of their background or circumstances. This impartiality fosters a sense of trust and respect between inmates and staff, which is essential for a safe and secure facility.

Furthermore, impartiality helps prevent discrimination and abuse, ensuring that all policies and procedures are applied uniformly. It also contributes to maintaining order and discipline, as inmates are more likely to respond positively in an environment where they feel they are treated fairly. The other factors mentioned, while important in their own right, do not directly address the core issue of fairness in inmate treatment as effectively as impartiality does.
