This is a quick post, expounding on what I have learned since I made the post on Those in power... a few days ago.
First of all, I have learned that delegates for Sanders were intentionally given the wrong information on the time and place of the meeting. I am unaware of any Clinton delegates receiving erroneous information, and all of the Sanders delegates did not receive that bad information. This can only mean that the Party wanted to make sure to "shave" any votes in Clinton's favor.
Second, the initial votes on rules changes were held while many Sanders delegates were still outside the hall, in line trying to register. I have heard it both ways that the vote was held earlier than scheduled, or not delayed because there were delegates were still filing in.
To show the other side of things, I have heard that many Sanders delegates were not properly registered in time. Remember, Sanders was an Independent who only "caucuses with Democrats." He had to join the Democrat party to run against Clinton. I guess not all of his followers did the same thing. As far as the "rapping the gavel and walking off," I have also learned that that meeting had run a couple of hours over the scheduled time and the hall had to be cleared, plus the cost of security was about to go way up because the security personnel were going to start getting overtime.
As it has been said before, "The truth is a three-edged sword; your side, my side and the truth." No side is totally right, no side is totally wrong. I always look at the facts of the matter and what the truth actually is.
