In wake of the Charleston church shooting, some activists are calling for new gun control laws. But, are new laws really effective in ending gun violence? And, do they violate our Constitutional rights? This week on Up For Debate, Julie Roys will discuss gun control with David Barton of Wallbuilders, who opposes it - and Michael Austin, an ethics professor, who supports it. Hear both sides and join the discussion this Saturday at 11 a.m. Central Time on Up For Debate!
