Well since I don't have the power to change the rules, I can only complain. Yes, a handball on the line should be goal awarded, not PK, because the probability of that ball getting in the net is 100% before contact with the hand. The PK is less than 100%, as we can attest.
Cannot be enforced, and will never be. How do you determine "will be 100% in the net" when they can't even determine a goal sometimes?
