Further excerpts from what the OP stated in this thread:

• "that class of submarine also happens to be the only type in service with the us navy that has a diving trunk capable of deploying and retrieving seal teams while remaining submerged. needless to say they dont just let anyone serve on these things. nukes (as in navy nuclear reactor technicians) even see it as an elite assignment, despite the trust already placed in them and the numerous psychological screenings and background checks they endure, and most are relegated to the surface fleet and stuck on aircraft carriers."

• "the basic point is that in the course of their duties, however numerous or divergent, they most likely accessed the same areas of the ship in a similar capacity and therefore were exposed to similar phenomenon, stimulus, information, sights, experiences or which ever term you want to apply. coincidentally, both of these people become involved in shootings with civilian federal employees where they die from an insinuated suicide over a relatively short span of time. notwithstanding my lack of acute clarification over the scope of their duties on board a ship, does this not seem to you somewhat anomalous?"

• "i dont have all of the answers. i only have information that leads me to believe a certain situation is more likely than another. why it was in dry dock to begin with, we will most likely never know, but it is obvious that if it was swarming with contractors at the time, as you say, then it makes it all the more peculiar why this small group for some reason stood out to him or moved him to actually fire his weapon. in the investigation done by the navy it doesnt seem to identify that any witnesses were present aside from the petty officer of the deck (if there were any others) and doesnt state whether or not he gave them commands before firing on them. re-reading it it does say explicitly that the dry dock was at pearl harbor and not san diego. the conclusion is contradictory in that it states he was unfit for duty and most likely psychotic, yet was serving on what could be considered one of the most sensitive platforms in any military branch. furthermore he was screened and approved for armed patrols in this capacity. during this time he was never once reported to counterintelligence or any authority through any insider threat reporting procedure. this conclusion is of course drawn posthumously."
