In a major blow to Police Commissioner Raymond Kelly and Mayor Bloomberg, Gov. Paterson has decided to sign a controversial bill barring the NYPD from keeping a database of people stopped and frisked on the street but not arrested, the Daily News has learned...The New York Civil Liberties Union and key members of the minority communities pushed Paterson to sign the bill, saying it creates a database that targets innocent blacks and Latinos. "This bill is an important civil rights bill that is in keeping with everything he's fought for during his political career," NYCLU executive director Donna Lieberman said.
