With such an effort, we can make sure our criminal justice system serves all and not just some. Together, we can raise the level of mutual trust that policing is built on -- the idea that police officers are members of the community they risk their lives to protect, and citizens in Ferguson and New York and Cleveland, they just want the same thing young people here marched for 50 years ago -- the protection of the law. Together, we can address unfair sentencing and overcrowded prisons, and the stunted circumstances that rob too many boys of the chance to become men, and rob the nation of too many men who could be good dads, and good workers, and good neighbors.
