The Dark Knight Trilogy: 10 Moments That Make No Damn Sense
10. The Bit When Batman Begins
When the Wayne family leave the opera on that fateful night, they exit through the back door into a very suspicious dark alley where they are somewhat understandably killed by a wretch lurking in the shadows hungry for pearls. Now, this is clearly a reference to the source, but that doesn't make it any less stupid.
Why exactly would they not use the main entrance? What sort of health and safety warden on the premises would allow them to leave out of a side door, into a dangerous alleyway, which is presumably a hotspot, given the fact that the robbery/murder never seems particularly opportunist.
It might be to keep up the appearances but why would the Waynes actually care? They are supposed to be down to earth and thoroughly democratic, and not exactly overly concerned with pretenses: they care about Gotham, not the way how the high society would consider them. And yet they sneak out and are murdered for fear that some snooty upper class twit would sneer at them - presumably with the twits wondering why the Waynes have just sneaked out of a back door.
That mentality was probably also why they didn't keep bodyguards with them, even when walking around with their son and expensive jewelry and such, but they can't have been so blinkered in their love of Gotham and urge to protect it (presumably from people who murder others in alleys) that they weren't aware of how dangerous the place can be at night. So why use the back door?
Also, everyone knows that when a gun is aimed at you, you arent supposed to make any abrupt movements, lest the person actually holding the gun pulls the trigger, reacting to sudden changes in the environment around him.
