As usual, there are technical issues/problems, human error, and then the group think issues when a bunch of people are trying to sort out a problem, especially when non-technical people are trying to make decisions on a technical problem.
I echo what a friend of mine said on this a few weeks ago. We are hearing all this chatter/anger over what the city officials did or didn't do, what the Emergency Manager did or didn't do and what the Governor did or didn't do. What were the Engineers saying? Who's running that plan? What was the approval process for the water system to be activated? Who over sees that?
