This is what is known as post hoc ergo propter hoc reasoning, i.e., water must have flooded the car deck as in the Herald of Free Enterprise. However, to do this, the bow visor must first have been compromised. Therefore it must have fallen off and taken the car ramp with it but as two people claim to have climbed down the car ramp, then the bow visor must have left a gap at the top of the car ramp for the seawater to seep in. That should keep the plebs happy whilst we slap a 'classified' label on what really happened.
It wouldn't do for POTUS Bill Clinton peace-maker extraordinaire between Israel and Palestine to be exposed as the person prepared to use a thousand civilians as collateral damage whilst smuggling out weapons for Israel on the Estonia public passenger ferry.
Look, it's fine that you report the opinions of those you don't agree with, but you should point out precisely what you're advocating, insofar as you have some theory at all.
You've been saying for some time that there were bombs planted at the bow visor (at least that some folks claim so). Now you're saying that the theory the bow visor failed and water rushed in is a
post hoc fallacy because the ramp was still in place[1]. If so, the whole theory that explosions blew the visor off would also be rejected.
So, you do need to figger out this: Was there damage to the visor that occurred, in your opinion? Or did the only damage that allowed water to come in occur at the one hole on the starboard side (rather smaller than the opening at the bow ramp) and that was the entire reason the ferry sunk within a short time?
I do like, however, the addition that this wasn't just about intelligence smuggling. Now Bill Clinton himself is secretly running guns to Israel on a ferry traveling to Sweden! That's good. But don't talk yourself out of the bombs planted at the bow visor. We really do need the explosions and the minisub planting a mine in the storm doesn't really do it for me. It's creative, but I just can't see it. So, please, whether the minisub stays or goes, we need some proper bombs for the story to work.
[1] You are, of course, confused when you call it
post hoc. A
post hoc fallacy is when one recognizes that event
A occurred before event
B and concludes fallaciously that
A therefore caused
B. When one commits such a fallacy, the error is in presuming the causal relationship. It doesn't follow that
A didn't occur at all.
