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: This is actually true to the comics, where a regular thug named Joe Chill was the killer of Mr. and Mrs. Wayne. There is no connection between this movie/series and Burton's "Batman"; they are separate takes on the same story, which is why things can be radically different. Burton chose to alter the storyline to give Batman an even greater reason to go after the Joker, that's his decision. Nolan chose otherwise in his presentation of the Batman legend, sticking to the original story.
