Is your point that we should be careful about raising concerns over 37,200 needless deaths in a year because of what happened in 1776?
Parts of America are as wedded to their right to own firearms as we are in the UK to the NHS: it's at the very core of national identity. It's going to take something big for those states to restrict firearms in any way but until that action is taken then one risks their life everyday by just going to school, going to a concert, going to the cinema, going to a shopping mall, going to a bar....the list is getting longer.
