Guns leading cause of death now for kids in the US. Same for other 1st world countries? Or no just us?
Guns aren't a part of the equation in other countries. They are a part of the equation here. And that's not going to change.
What is the leading cause in other countries?
In the US, car auto deaths dropped from 10k to 7k thanks to safety improvements in vehicles, increased cost of of vehicles and insurance, reduced miles driven per person, fewer kids driving at 16, and increased education for kids who do drive.
Violent crime and murder (as well as suicide) increased with tumultuous times. As it always does. Not to mention, our population increased nearly 20% which would account for over 60% of the increase by itself...
Is there any evidence that guns have caused a larger increase for the US than other countries? If so, you might be on to something... But then, even so, the 2nd ammendment isn't going to change.
The only way we'll improve it would be to increase our gini coefficient.
*Edit* and "kids" being up to 24yrs old... Which includes all of the gang related shootings. Which no laws or restriction could possibly impact. Again, increased gini coefficient solves this problem better than anything. Everything else is a wasted effort.
