In this second hour of Midday, we continue our conversation on the racist killings in Charleston. The alleged shooter’s motivations appear clear, based on what he said and on a manifesto he published online; however, some have raised questions about 21-year-old Dylann Roof’s mental state. Dr. Gordon Livingston talks about violent behavior and the ability of mental health professionals to predict and prevent it. And we turn to news in Baltimore, with police commissioner Anthony Batts saying that reform comes with a cost, and that raising standards in the city will likely result in more officers being forced out of the department. University of Baltimore law professor J. Amy Dillard joins us for comment. We’ll also hear about efforts to match nearly 8,000 Baltimore kids with summer jobs, and meet a banker who got his start with the city's Hire One Youth program.
