Poor Joe Root

I feel very sorry for Joe Root...no evidence he edged it but much suggesting the contrary and yet he's gone.   No problem with the technology, but once again the implementation of it that's the problem.   Instead of the batsman having the benefit of the doubt, the bowler got it.   And, although I didn't see it, I gather it's the second time in the day as the same happened to Steve Smith.

The only way round this is to get over the worry about taking responsibility away from umpires.   It shouldn't matter what their original decision is - if there's no evidence to prove the batsman is out then it's not out.
