Blindness

The blindfold and blade allusions remind me of the personification of Justice. As seen in statues commonly found in courthouses, Justitia is portrayed as a matron carrying a sword and measuring balances, and sometimes wearing a blindfold.

• sword: a double-edged sword in her right hand, symbolizing the power of Reason and Justice, which may be wielded either for or against any party.
• measuring balances: set of weighing scales typically suspended from her left hand, upon which she measures the strengths of a case's support and opposition.
• blindfold: justice is (or should be) meted out objectively, without fear or favor, regardless of the identity, power, or weakness: blind justice and blind impartiality.

I want to say the song is about the concept of justice and how it was the standard of objective truth until people started to push and distort it to their own means ("I was the one with the world at my feet "... "You gave me a life I never chose"). Distorted Justice's blind impartiality became apathy ("I was a blindfold, never complained") and left the victims ("survivors singing in the rain") to suffer, but their pleas are now answered and now it rushes to the rescue. A return of true justice ("Got us a battle, leave it up to me").
