> Humans can render other humans unrecognizable with a rock.
They are much less likely to.
We have instinctive repulsion to violence, especially extending it (e.g. if the rock does not kill at the first blow).
It is much easier to kill with a gun (and even then people need training to be willing to do it), and easier still to fire a missile at people you cannot even see.
Extreme violence then? With rocks, clubs of bare hands? I was responding to "render other humans unrecognizable with a rock" which I am pretty sure is uncommon in schools.
Not in public schools in the British sense. I assume it varies in public schools in the American sense, and I am guessing violence sufficient to render someone unrecognisable is pretty rare even in the worst of them.
