Cover art for Robbers lyrics by Cold War Kids

I'm going to take this in a different direction:

I believe this song is political. Cold War Kids are using the analogy of a robber or thief to represent the government leeching off of its citizens.

They explain in the song how they rob from the "blind" people of the nation much like a robber would. However, "not me, I'm knockin" implies that they are not trying to hide it; i.e., taxes.

The catch is, the people of the government are citizens as well: "don't think I don't know sympathy / my victims in my shadow / starin back at me" where the victims in "my" shadows are themselves.

my thoughts exactly, you worded the part about the victim in my shadow well. thank you!

there are a few misprints in these lyrics

sulkin' walkin' 'round the city after dark need protection from street thugs who clip the locks and rip the doors off rugs like cowards

and maybe even further, its not just about the government, but perhaps the blind citizens themselves keeping this insane imbalance in existence. robbing themselves so to speak. consumer nation if you will.
