He and his family will fear for their lives for the rest of their days. That's the real sentence. One has to be naive to not think there's a chance he doesn't walk out.
He will forever be a murderer and his name will only be remembered in history as the face of Chicago Police abuse, and the first one that got caught, not as a man that had the courage one day to sign up to put his life on the line every day for his family and city. His poor daughter will have to carry this, the cognitive dissonance of her father being a murderer and a YouTube clip only two clicks away.
CPD and the justice system can do their silly song and dance, but they don't actually care about these hard truths. If they did, things would be different.
