An estimated 3,000 people have been killed due to gun violence since the Newtown shootings in December of last year. But the emboldened push for greater gun control that followed the aftermath of the Sandy Hook murders which left 20 children dead appears already to be losing strength. some gun control experts say that an assault weapons ban would do little to reduce gun violence and could hamper more effective legislation. Could such proposals be more harmful than helpful in the campaign to reduce gun deaths in the US? Joining Inside Story Americas, with presenter Shihab Rattansi, are guests: Adam Winkler, a constitutional law professor at the University of California and author of the book Gunfight: The Battle over the Right to Bear Arms in America; David Hemenway, a professor of health policy at Harvard University; and Robyn Thomas, the executive director of the Law Center to Prevent Gun Violence.
