Death and violence is not going to end, subject to a total remaking of the world.
Indeed mate - though many places in the world thankfully don’t have as many (or anywhere near the number of) school shootings.
We should focus on making schools safe! For the particular story I’m commenting on, would we rather this domestic dispute happened off campus? Sure, but I don’t think that’s the most important thing that happened her. Nor would I have been more pleased if a car or knife had been used.
This will sound really morbid, but at least if a knife were used, you could take solace in the fact that, if you were a witness, you need only maintain a safe distance of a few feet from the criminal to be pretty much safe. And, you would likely survive even if you were stabbed.
