I want it to end with the perpetrator room temp and no one else hurt.
As far as the terrorist vs grudge these sorts of mass murder events at usgov facilities seem to be heavily weighted toward terrorist perpetrators. Otoh if i see a killdozer as the tool of vengence i will think grudge.
Personally, I think the word "terrorist" has been overused and politized into a nonsense word at this point.
To me it always meant an act designed to inspire terror amoung a populance for a specific, caculated reason and message.
These lone shooter incedents don't have the same feel. Regardless of the wacked out rantings of the perpatrator, the terror is seems more designed as a momentary thrill and a power trip for the induvidial doing it. It's evil and it's pyschotic, but it's not the calcualated and ruthless design of a bigger picture.
The worst part is, by labeling these guys as "terrorists" we add to their thrill.
