Even with the internet, we don't know as much as we think we do, and we still get trolled hard by the authors sometimes. RIP was massive reader-trolling at the time. You had people swearing they'd never read another Batman comic ever if Alfred was the Black Glove, or if Bruce's father was a murderous super-criminal. Batman was "going to die" and people were mad about it, even though the first issue blatantly references him dying in the issue just before RIP (naturally, RIP comes after a death, not before). You still have people say that he died in RIP or in FC.
