I'd add "right" and responsibly.
Right just means they hit what they are aiming at, and this describes a lot of these "shooter" A-holes, walking into schools, and other softly defended places and opening up.
Responsibly, goes on to bring in "life" and all things living, and your relationship with them, be they animal, or human. And then having respect for it. I may be way wrong, but my belief is these shooter a-holes lack that in any manner. I know one thing for sure, that "GUN" even if it is big black, and evil looking, NEVER shot anyone by itself, so to blame it, isn't the correct path to making this growing problem go away. People need to get fixed, or it will still be softly defended spots, but it will be baseball bats, knives, or something else that gives these defective people an advantage. I'll know this has changed when these pussies walk into a gun show, and start shooting.
