.....It might be simplistic but in the UK we can look at the prevalence of guns in USA and the number of gunshot fatalities/school shootings etc. and draw a very obvious conclusion. I think perhaps in the USA you are too close to the problem and maybe failing to see the wood for the trees.
It doesn't take a huge leap to make the case that something similar would be true for knives.
No, I see the problem easily enough, and yes, the same holds true for knives as well. See below for further elaboration.
......Off topic: it is not the number of guns in the US that correlates to the number of gun related crime. Europe except UK has also lots and lots of guns.
The difference is that in Europe we have a permit system, where the applicant is vetted.
In the US any nutcase can buy........
We've always had guns readily available for over 2 centuries. In the car, on the living room wall, bought over the counter at the local hardware store (or even by mail order from Sears & Roebuck back in the day) All without any real problem until violent crime began going up in 1960 until it reached a high point in 1994. The something amazing happened; gun sales started climbing exponentially and continued to climb until last year. Beginning at the same time (1994) violent crime (specifically, gun crime) started dropping until in 2014 it was at the lowest point it had ever been. However the gun crime starting in the 1990s and still going on is particularly dramatic; i.e. the school shootings or mass shootings with no apparent motives that draw headlines.
There are more restrictions now than there have ever been:
1) either be in possession of a Concealed Weapons Permit or suffer a 3 to 5 day wait before buying a handgun in EVERY state
2) no handgun purchase at all without a permit in some states
3) restrictions on where firearms can be carried
4) background checks before purchase (does not apply to private sale)
These are the most obvious restrictions but numerous more in varying states.
What's changed that makes more senseless crime (killing simply for the sake of killing) the current trend? It's not the gun itself (or knives in y'all's case) It's not licensing or lack of it. And no, it's not "mental health." It the steady decay of morality and the rising sense of entitlement. Every shooter so far has displayed that sense of entitlement in their stated reasons for their rampages (fired employees, failed students, racial bias when the shooter attacked the black church, etc.)
But as a society it's so much easier to blame the objects (guns or knives) and try to ban or restrict them. Or it's so much easier to blame "mental illness" and pass feel good laws about treatment and background checks (only 2 of the numerous shooters have had anything on their records that would have red lighted sales and 1 of those had nothing to do with mental health) Yeah; that lets us avoid the hard work rooting out the causes for moral decay and reversing it. It would mean we might have to stop the practice of giving every kid a spot on the teams whether he/she passes the try-outs or not. It might mean we stop giving little Johnny a trophy just for showing up to play even if his team loses every game. It might mean we have to start teaching our kids that life's not fair and they won't always get what they want. It might mean we have to start parenting again and raising kids that value human life and the rights of others rather than thinking they're the center of the universe. Naw, that'd all be too much work; lets just pass some more laws that won't work and pat each other's backs (giving each other that participation trophy like we give the kids)
