Now
I must start by first stating that I have NO IDEA about explosives, and so on, but that being said, I would think that anything exposed to sea water for that long would not be too much good any more... Explosively that is.... Unless the thing was so well sealed that it is still dry inside, or moist, as one of he other posters mentioned. I have read about aircraft found from this same era, that still had inflated tires! Now one would have to think that a war head or what ever they are called, would be sealed better than a simple tire, so I would think they have an unstable a bomb in thier hands with unknown potential to cause great harm.
The problem I see here is two fold. #1, you have in "someones" possesion, an unknown commodity of explosives, but at least we know it's ALOT!!!. That alone would cause me to give those guys a "here's your sign" sign award. That being aside, you have the problem with looting a wreck, that most likely have remains of the brave soldiers, who fought so valiaintly and proudly, (on all sides) This needs to be respected IMHO. We ALL need to have respect for those who gave the ultimate sacrifice. Respect the graves of those resting there. I say take that thing back and put it back where it came from or call someone who can dispose of it properly. And in the end... well I guess the big boss will have to decide if what they did was so bad. To me its is beyond discriptions I can use here on this forum. I would call the Police right away If I had any knowledge of this sort of thing. Just my opinion of course.
