Not surprisingly, as civil rights advocates converted a grassroots movement into a legal campaign, and as civil rights leaders became political insiders, many civil rights organizations became top-heavy with lawyers. This development enhanced their ability to wage legal battles but impeded their ability to acknowledge or respond to the emergence of a new caste system. Lawyers have a tendency to identify and concentrate on problems they know how to solve—i.e., problems that can be solved through litigation. The mass incarceration of people of color is not that kind of problem.
