One or two people have risen (slightly) to Walsh's defence, along the lines of "knock him down and he'll bounce right up again, and fix the problem."
While the ability to bounce back, and the tenacity to fix problems, are laudable qualities, these supporters are missing one major point.
For the sake of the passengers, the staff, the shareholders, and the very existence of the company, there should have been no need to 'bounce back.'
Walsh should have got it right the first time. He didn't.
