Than why would the tombstone say 9-22-04 as the date of his death? I think he could still be alive, but I'm just not sure.
I'm pretty sure this is a cover up. Notice how the Oceanic 6 previously claimed that they were the only survivors from the crash other than one person who died on the island(can't remember who they said?). Jin most likely died on the island, but because of what the O6 have discovered or are hiding(which we still don't know) they said he was killed on the actual crash. We obviously know this isn't true. That is my guess on why the date of his death is labeled as the day of the crash. Hope this makes sense....any other thoughts???
i doubt it's a cover up since hurley and sun were mourning at his grave all by themselves. just my 2 cents.
They aren't covering up the fact that he is dead, but the actual date of his death. Sorry if I didn't make that clear. The O6 are obviously hiding something and have a fabricated story that they are telling the rest of the world. We surely won't find out all of these details any time soon. Maybe in a few seasons....
