Marshall of the University of Louisville School of Medicine and writer of a vaccine handbook for doctors. ‘For our children’s sake, we need to think like scientists,’ said Marshall, who was not mixed up in new study.Firearms played a role in 83 % of youth homicides, and about half of suicides involved a gun, Xuan said. Within their study, the researchers graded states on their gun laws using an annual scorecard released by the Brady Center to Prevent Gun Violence. The scorecards consider efforts to curb firearm trafficking, strengthen criminal background checks, ensure child safety, ban military-design assault weapons, and restrict guns in public places. The analysis authors found substantial variation in state-level gun laws scores with typical scores ranging from a low of just one 1.3 in Utah to a higher of 79.7 in California.
