According to a recent study, the shooting death of Trayvon Martin and the acquittal of his killer is not unique. In "Operation Ghetto Storm," the Malcolm X Grassroots Movement (MXGM) found at least 136 unarmed African Americans were killed by police, security guards and self-appointed vigilantes in 2012. Overall, one black person was killed in an extrajudicial shooting every 28 hours. We speak with Kali Akuno, a longtime MXGM organizer and author of "Let Your Motto Be Resistance: A Handbook on Organizing New Afrikan and Oppressed Communities." "This speaks to the mindset of criminalizing blackness," Akuno says. "We see it systematically throughout this country and really we have to get at the heart of it and have a much deeper conversation. I think the mass movement which is taking place in response [to the Trayvon Martin case] is an opening shot to have that conversation."
