Character mistake: As Bruce Wayne is researching the jewel thief, the word "Heist" is spelled "Hiest" in a newspaper headline. (00:15:45)
Character mistake: When Bruce is looking up information on Selina Kyle on his computer in the Batcave, at one point, "Kyle" is misspelled as "Klye."
Chosen answer: Given that no accurate records would have been kept of what occurred in Gotham during Bane's occupation, it would be very easy to claim that Bruce had been in the city when the bridges fell, been captured and subsequently executed by forcing him out on the ice, as had happened with many other socialites. Plenty of people died during Bane's takeover of the city, particularly in the final hours. There's no reason why Bruce would stand out among them as a candidate, and even if anybody did harbour some suspicion, it could hardly be proven.
