Again, even if people have suspicion of Batman being around, that goes against him vanishing. It's just that easy.
Nope, it doesn't. Because if there's no proof or evidence he's still considered to be vanished and gone from the originally reported date.
If someone reported seeing Batman but had nothing to back it up, their claim becomes discarded. That doesn't mean Batman is back at all. It means someone made an unsubstantiated claim that they saw Batman.
LOL how are you guys even drawing the conclusion that someone's unconfirmed, unsubstantiated claim means Batman didn't retire at the end of TDK, or that this somehow conflicts with Nolan's quote? Nobody's disputing that at all.
There is no crossover or conflict of interest between:
a) Batman retiring at the end of TDK
b) someone claiming to have seen Batman
We saw Batman wannabes in TDK. Is it impossible one of those guys tried to be Batman after Harvey's death? Nobody is saying this actually happened, it is a hypothetical scenario based on what we know from the movies and how people might behave in the wake of Batman's disappearance.
People have claimed to see Jimmy Hoffa, Amelia Earhart, and other famous individuals who 'vanished'. Does that mean those people didn't disappear, just because someone claimed they saw them? Nope, it doesn't. Last I checked they're still regarded as missing/disappeared/vanished since the original reported dates.
Nobody says, "Oh, someone claims to have seen Jimmy Hoffa. That means he didn't vanish." They say, "Oh, someone thought they saw Hoffa, but there's no proof. So, he's still missing since 1975."
