State-by-State Gun Law Database

(Originally aired June 6, 2017) Guest: Michael Siegel, MD, Professor of Community Health Sciences, Boston University Because relatively few gun laws have been passed by Congress, it’s up to individual states to decide if, for example, you need a permit to carry a concealed weapon. Or if someone convicted of domestic violence can have a gun. The number of gun laws on the books in each state varies dramatically: California has 104. Alaska has just 4. A comprehensive new database of state gun laws offers a way to track the effects of restricting access to firearms.
