All these school shootings . . .

When and why did people, especially students, get the idea they could just take a gun or guns and start killing people in classrooms? Isn’t there something else they could do to express their angst? How about punching a bag or a wall? And why are they just shooting anyone, even the nice person in row three who once lent them a pencil or made a place at the lunch table for them?

A lot of question marks.
