whats the use of having technology if you do not ant to use it?
I talked about this in the thread, it doesn't matter if Hotspot doesn't show an edge if other, more conclusive aids (like sound) show he did.
Hotspot still has it's uses, little gloves to close in fielders, etc.
It's an aid. I'm sure if there was no sound, but a white spot on hotspot you'd all be moaning that they didn't use the lack of a noise.
He hit it, Snicko confirmed the decision and the sound was distinctive. Though I do think it was a brave decision and I was surprised they overturned it, but the right decision was made.
Edit: To add to that, you use all the aids together to build a picture, it's evidence building, some evidence has more weight than others.
