Balance needed as penalties for some fouls outweigh the crime in GAA

In recent months I’ve attended weekly classes on philosophy. All the big ones and many more have been discussed. What is it about? What is just? In your given circumstance, what would a wise man or woman do? And given the part of the world we inhabit, where hurling is a way of life, over tea break we’ve ended up philosophising about it too.
One of our number is particularly reflective and insightful. He even has the beard to go with it. And something he remarked on would have you thinking deeply and differently about aspects of hurling, and not just life. Namely the ‘65. And the lineball whereby now a Joe Canning can punish you by cutting the ball straight over the bar, just because you may accidentally have touched the ball last — if you touched it last at all. Is that just, he wonders? If you were a rule-maker, what would a wise person in that position do?
