When students complain college seems like prison, scholars at one institution are being quite literal.

In the hallowed halls of Columbia University, a nest of ex-cons — who have served time for murder, attempted murder, robbery and assault — hold court on their unique brand of social justice for admiring students enrolled in the school’s social work program, a FoxNews.com investigation has found.

The ex-cons work for or with the Criminal Justice Initiative (CJI), co-founded in 2009 by former Weather Underground operative and Columbia adjunct professor Kathy Boudin, who pleaded guilty to felony murder for her role in an infamous 1981 armed robbery that left two police officers and a security guard dead. And while that case was well-publicized, the group is hardly upfront about the “practical experience” of Boudin and others associated with the CJI.

A description on the program’s website says it is “situated inside” Columbia, and a part of the school’s “Social Intervention Group,” a research center within the Columbia University School of Social Work. It lists among its goals helping to forge a solution for “a central social crisis of our time, mass incarceration.” The program holds events and conducts research as part of “an interdisciplinary project built around a model of community collaboration” that “seeks to increase the number of skilled practitioners, policy-makers and researchers who can advance the fields of re-entry and incarceration across all disciplines.”

But students and parents who shell out more than $43,000 in annual tuition and fees might be hard-pressed to uncover the fact that former inmates are running the CJI. Outside of a vague reference to Boudin and Cheryl Wilkins being “part of a community of people who have returned from prison,” there is no information about their criminal pasts. Boudin’s school directory bio, for example, makes no mention of her time in prison. Several other CJI faculty, program members and associates have similarly disturbing backgrounds.

Wilkins, co-director of the CJI, is listed in the Columbia School of Social Work adjunct faculty directory as a “research scientist” and “Associate Director for the Criminal Justice Initiative. She was convicted for her role in a 1996 gunpoint hijacking of a Federal Express truck in Harlem, in which she served as the getaway driver. Wilkins served a 12-year sentence for robbery and assault at Bayview Correctional Facility in Manhattan.

But Wilkins’ school biography page makes no mention of her time in jail. .
