The Dark Knight Exception

The Dark Knight  is a perfect example of exceptional sin, if there really is such a thing. Some people would say it is never right to steal even if it was to feed your starving family, or that it is not acceptable to run a red light in the middle of  nowhere. Certain  situations require a bit of a bend in a persons morals; if Batman and Lucius Fox were too righteous to use the cell phone sonar, two boats full of people would have been murdered. The Joker was in a building overlooking the river full of hostages with a detonator for the bombs placed on each boat, the sonar was a necessary sacrifice made in order to save the lives of many people. The film perfectly displays the rules of exception, sometimes rules and moral boundaries must be broken for the greater good.Yes, some of the people's privacy  was invaded but that action directly saved the lives of many.  This sonar would not be acceptable if it were used  daily in order to prevent crime, because the threat does not yet exist and that is a true invasion of privacy.
