I think the song is about resisting isn't always the best option. Usally, when you resist something you know you shouldnt, or can't, the only one who stands to get hurt is you, or worse-someone you love. The song conveys this by the fact that the man, who is resisting the police, has one gun. The police, have many more guns then this, maybe not twentyone guns, but that I soley for the songs fluency. The man is resisting the police, and he and his partner are the only ones who will be hurt-as he is resisting, when he has no hope of victory.
