Did a quick cursory search, so this may be a bit off.
Since the year of the birth of my grand-daughter (9 years old, U.S. resident), she has lived within 50 miles (a few quite a bit closer) of six mass shootings (31 dead, 105 injured). Didn't even try to compile those a bit outside that radius and deaths/injuries less than 4, holy smokes....
And yet, the U.S. addiction to, and lust for, high powered weaponry continues unabated. The latest dismal attempt by Congress is a bit like putting a Baby on Board placard on your vehicle and actually expecting the other drivers to change their driving habits.
Man, you Americans.......
