Sotomayor and the death penalty

The main part of the story here is that 300 or so boxes of additional material have just been found on Sotomayor. But there was also this info here:

Sotomayor served on the group’s board of directors from 1980 to 1992. Conservatives opposed to her nomination have seized on a 1981 memo signed by her and two other directors of the group, which is now called LatinoJustice PRLDEF. In it, the directors argued against reinstating the death penalty in New York state, making the case that capital punishment is racist because it is disproportionately imposed on minorities.
