Three years after Marcus Johnson's release, the legal system had transformed. The AI judicial system still existed, but it was no longer the final arbiter of justice. Every verdict it delivered was reviewed by a human judge. Every defendant had the right to challenge the algorithm's decision. And every decision was accompanied by an explanation - not just a probability score, but a detailed breakdown of the factors the AI had considered.

Sarah had been appointed to the Federal Algorithmic Accountability Commission, a new body tasked with overseeing AI in government decision-making. The work was exhausting, but rewarding. Every day, she and her colleagues reviewed algorithms, identified bias, and recommended reforms.

"The problem isn't AI itself," Sarah explained to a group of law students during a lecture. "The problem is how we use it. We treated algorithms as if they were objective, as if they could replace human judgment. But algorithms are just tools. They reflect the data they were trained on, and that data reflects our biases."

One student raised her hand. "But what if we could train AI on unbiased data? Could we eliminate bias entirely?"

Sarah smiled. "That's the dream, isn't it? But here's the problem: there is no such thing as unbiased data. Every decision humans have ever made has been influenced by our prejudices, our limitations, our imperfect understanding of the world. We can try to correct for bias, but we can never eliminate it entirely. That's why human oversight is essential."

After the lecture, Sarah returned to her office to find a stack of case files waiting for her. The commission was reviewing appeals from defendants who had been convicted by the AI system before the reforms. Each case represented a life that might have been changed by an unjust verdict.

She picked up the first file and began to read. A young woman named Destiny Williams, convicted of fraud based on an algorithm's assessment of her spending patterns. The AI had flagged her transactions as suspicious, but a human review revealed that she had been caring for a sick parent, making unusual withdrawals to pay medical bills.

One by one, she worked through the files. Each case was a reminder of why this work mattered. Each overturned verdict was a small victory in a much larger battle.

The reforms were working. But the work would never be finished. Justice, Sarah had learned, was not a destination - it was a journey.
