In most of these massacre cases people drop the ball. The way they drop it is by not taking responsibility for the situation. The professor/shrink in aurora who ignored the threats including drawings. The VA tech shooter whose parents shipped him off to school without treatment.

what about the dad that couldn’t handle having a troubled son and ducked out leaving the mom holding the bag
