So, I am currently replaying Silent Hill 2 and a few hours ago I finally arrived at the Toluca Prison and something in the cells drew my attention. I remember the same thing happening pretty much each time I played the game. I looked it up on this board and didn't find any trace of it, so here it goes (in case it is something I missed out and that has already been talked about, just lock this topic I guess )
In the cell in which you find the Oppressor tablet, am I the only one who noticed that before you can exit it, the door is blocked and James comments saying the bars are unbreakable or something like that? I play the game with French subtitles so I am not sure what the translation would be and I actually didn't really pay attention to the exact terms that were used and since it happens only the first time James gets in there, I could not check it out again.
Now that I know that the tablets represent James, Angela and Eddie, I was thinking that maybe locking James in the cell for a few seconds was a hint given by the SH creators to help us realize that this tablet represents him and that this cell is actually where he should be. Or maybe it's just a glitch I get but all I can say is that we do get in two others cells (with closed doors) and this "locked door thing" only happens in this particular cell!
Thought I was the only one who ever noticed that. I thought it was a glitch too, but since it happened to you I guess it's part of the game. Your theory seems to be correct -- it being a reference to his "Oppressor" role.
