Your conviction is correct. I do consider myself smarter than the average Bear(Kat).
But let's say that something similar happened in 2016, and my playing partner, in a club championship match for instance, says, "Your forearm was touching your torso on that putting stroke. So I win the hole."
And I say, truthfully, "Well, I always hold my forearm away from my body on my putting stroke, so if it was touching, it wasn't intentional.'
It's almost impossible to prove "intent" in a court of law. Can you imagine the arguments and hard feelings this could cause on a golf course, when the "judge" is in the pro shop selling shirts or on the driving range giving a lesson?
