Take away the 2nd Amendment paranoia and fear of crime in a gun society and we could all experience the same.
Pretend guns had been collected up all over the world in a big bundle and thrown into the sun courtesy of the man of steel (that's not a porn reference
)
. So now a government says we all have the right to bear 6 inch knives. The result is all the criminals carry them hence the public start wanting them for self defence from the criminals and younger people think they are cool so carry them too.
Then two people get into an argument, get physical and out comes a knife. Some people get drunk, get physical and out comes a knife.
Forget knives and say we are allowed to carry broken bottles or screwdrivers. Same result.
You put it there and someone will always use it in situations like above. It's just common sense.
I do think changing a society so close to it's guns might mean phases so as to improve public confidence less criminals have them. But at some point you have to get rid.
No doubt then you will need a new Trump wall to stop all the guns coming up on the backs of migrants...
