*From a phone call to the NY State Assembly Information line:
The bill number for the law that amends the Rockefeller laws, signed by Gov. Pataki on Dec. 14, 2004, is assembly bill A11895 (2004), chapter 738.

*The only free online source I was able to find for the full text was at the Center for Community Alternatives site (older bills seem to disappear off the state assembly site). The pdf is here.

*And more info. from the Center for Community Alternatives on the Rockefeller laws is here.

*As for as total percentage of black and latino inmates serving time under the Rockefeller laws, I found a 94% statistic from the New York Civil Liberties Union, which cites the Correctional Association of New York. The report from the (Correctional Association of New York actually states 93%.
