A d
ispute about parking spaces led to two deaths. Given that the shooter is 74 years old and the victims were nineteen and eighteen, it's pretty unlikely that a society without easy gun access could have resulted in these senseless deaths.
The NRA probably would argue that the two teenagers should have been also armed. Then the deaths might have been only one (the 74-year-old man) or three (all of them). Without any guns at all, the quarrel would probably have passed without physical damages.
But what do I know.
