Visible crew/equipment: When Bruce/Batman arrives with the Tumbler on the car parking's roof in attempt to bring Rachel to the Batcave after she was poisoned and he's surrounded by the cops cars, most of the cast and crew members are visible hidden into the elevator waiting area while the SWAT helicopter illuminates the entire zone.
Visible crew/equipment: During the first board meeting at Wayne Enterprises, in two close-ups of Mr. Earle, spots of bright green light from the movie camera is reflected in his glasses. The same thing happens when he opens the door and sees Bruce. There is no such light shining in either room. (00:46:10)
Answer: First, he follows it up by saying it's because Bruce's father failed to act against Joe (to try to stop him), implying that his father was weak and a coward. But overall Ducard's stance was crime cannot be tolerated. "Criminals thrive on the indulgence of society's understanding." The League had tried to destroy Gotham before with economics, but men like Thomas Wayne tried to help the poor and he was killed by the same people he tried to help. In Ducard's mind, had Thomas Wayne not tried to help the poor and criminals, he wouldn't have been shot.
