The FBI will never let a bunch of cleaner's sweep the exploded room. Even if they sweep the room; what they collect is not garbage, It's called evidence until the case is completely out of court.
In the end credits, the last name of Inside Man (2006) writer Russell Gewirtz is misspelled as "Gerwitz".
Early in the movie, the robbers set up an impromptu foundry to melt some gold. With how much gold there is, the foundry would be working for a long time, thereby creating an enormous amount of heat and fumes. There is no air cleaning system in place and the robbers barely break a sweat at best.
The Federal Reserve Bank in Manhattan, New York are is heavily fortified. The very beginning of the film shows only a few security people with 1 or 2 armed guards in the "Public Tour" area, which this film is depicting. This is completely in error, as there are at least 1 or 2 squads (12 to 24) if not more heavily armed, and very, very well trained agents working there. None are on the order of "Security Guards" you might see in a small bank or large office building. This is a colossal plot hole. Remember, there is more gold here than at Fort Knox, Kentucky.
