Hillary Clinton was pressed on her record on racial issues during a 15-minute meeting last week in New Hampshire with Black Lives Matter activists, video released by the the group shows.
Activists asked Clinton about mass incarceration, racial tensions and crime legislation passed under her husband's administration.
"I don't believe you change hearts," Clinton said when asked what she would do to change hearts and minds. "I believe you change laws, you change allocation of resources, you change the way systems operate. You're not going to change every heart. You're not."
Activist Daunasia Yancey told MSNBC's Melissa Harris-Perry, "What we were looking for from Secretary Clinton was a personal reflection on her responsibility for being part of the cause of this problem that we have today in mass incarceration, and so her response really targeting on policy wasn't sufficient for us."
