Rule Six??? Sure. But he worked his way up:
1. All guns are always loaded. Yep. He demonstrated that by direct action.
2. Never let the muzzle cover anything you aren't willing to destroy. Probably; even though he appeared to be willing to "destroy" a college-town policeman. Twice.
3. Keep your finger off the trigger until ready to shoot. News reports suggest poor trigger-finger discipline.
4. Be sure of your target and what's behind it. Definite fail on the second part.
"5. Never try to catch a dropped gun." Whattaya know, there's no evidence he broke this unofficial addition!
But as for Rule Six, total fail:
"6. Put something on, for pity's sake!" The headline, Bloomington cops shoot naked gunman near IU campus, tells just about the whole story.
No one hurt but the shooter, which strikes me as an okay outcome.
