If there is a tacit acceptance that negligence was possible however; the argument is that it should not have been documented as such under the rules of the day; then is it not the case that a large part of what this campaign manages to achieve is to contiinue to highlight the probability that the crew were negligent and is this not counter productive?
Fair enough, you might sometime in the future get the finding changed but is it really worth continuing to drag this along and continue to highlight the fact that they were probably; but not definately; negligent?
The aim might be well meaning but it would seem to the uninitiated a tad counter-productive.
