Powerful infographic from the FiveThirtyEight.com website (to whom all respect for numbers-led analysis and comment). Gives the question some context and perspective. And #ContextMatters. (Red dots are suicides, blue are homicides, yellow are accidents)
Overall, 33,000 people a year die from shootings in the USA. That IS a big number.
