Alexander served as director of the Racial Justice Project at the
American Civil Liberties Union (ACLU) of
Northern California from 1998 until 2005, which led a national campaign against
racial profiling by law enforcement. She directed the Civil Rights Clinic at
Stanford Law School and was a
law clerk for Justice
Harry Blackmun at the
U. S. Supreme Court and for Chief Judge
Abner Mikva on the
United States Court of Appeals for the D.C. Circuit. As an associate at Saperstein, Goldstein, Demchak & Baller, she specialized in plaintiff-side
class action suits alleging
race and
gender discrimination. Alexander was a visiting professor at
Union Theological Seminary in the City of New York from 2016 to 2021. In 2018, she was hired as an opinion columnist at the
New York Times. There she collaborated on a piece with Leslie Alexander entitled "Fear" which became a chapter in
Nikole Hannah-Jones's "
The 1619 Project."
The New Jim Crow Alexander published her book
The New Jim Crow: Mass Incarceration in the Age of Colorblindness in 2010. In it, she argued that systemic
racial discrimination in the United States resumed following the
Civil Rights Movement, and that the resumption is embedded in the US
war on drugs and other governmental policies and is having devastating social consequences. She considered the scope and impact of this to be comparable with that of the
Jim Crow laws of the 19th and 20th centuries. Her book concentrated on the
high rate of incarceration of African-American men for various crimes. Alexander wrote, "Race plays a major role—indeed, a defining role—in the current system, but not because of what is commonly understood as old-fashioned, hostile bigotry. This system of control depends far more on racial indifference (defined as a lack of compassion and caring about race and racial groups) than racial hostility—a feature it actually shares with its predecessors."
The New Jim Crow described how oppressed minorities are "subject to legalized discrimination in employment, housing, public benefits, and
jury service, just as their parents, grandparents, and great-grandparents once were."
The New Jim Crow was re-released in paperback in 2012. As of March 2012 it had been on the
New York Times Best Seller list for six weeks and it also reached number 1 on the
Washington Post bestseller list in 2012. The book has been the subject of scholarly debate and
criticism. In the fall of 2015, all freshmen enrolled at
Brown University read
The New Jim Crow as part of the campus's First Readings Program initiated by the office of the dean of the college and voted on by the faculty.
Yale University clinical law professor James Forman Jr., while acknowledging many similarities and insights in the Jim Crow analogy, has argued that Alexander overstates her case for
decarceration, and leaves out important ways in which the newer system of mass incarceration is different. Forman Jr. identifies Alexander as one of a number of authors who have overstated and misstated their case. He asserts that her framework overemphasizes the war on drugs, and ignores violent crimes, arguing that Alexander's analysis is demographically simplistic. Alexander refers to
electronic ankle monitoring practices as the "Newest Jim Crow," increasingly segregating people of color under bail reform laws that "look good on paper" but are based on a presumption of guilt and replace bail with shackles as pre-trial detainees consent to
electronic monitoring in order to be released from jail.
Hidden Colors 2 Alexander appeared in the 2012 documentary
Hidden Colors 2: The Triumph of Melanin, in which she discussed the impact of mass incarceration in Black communities. Alexander said: "Today there are more African American adults, under correctional control, in prison or jail, on probation or parole than were enslaved in 1850 a decade before the Civil War began.
13th Alexander appeared in the 2016 documentary
13th directed by
Ava DuVernay. As an interviewee, Alexander described the evolution of racial disparity in the United States of America through its evolution from slavery, the Jim Crow laws, the war on drugs, to mass incarceration. Alexander said, "So many aspects of the Old Jim Crow are suddenly legal again once you've been branded a felon. And so it seems that in America, we haven't so much ended racial caste but simply redesigned it." ==Personal life==
