I think we need to fight the tendency to create new rules or laws when something goes wrong. The original 4 would have prevented this, so no need for #5.
Some may disagree, but I always stress #2 (muzzle discipline) as the most important rule. That way if you make a mistake on one of the others you and the people in the immediate vicinity will be:
1) Scared
2) Angry
3) Embarassed
But more importantly:
4) ALIVE
