the part about "wherever there's a cop beatin a guy..." and that whole thing is taken from the most famous passage in The Grapes of Wrath, where before Tom leaves his family, he tells ma that no matter where he is, he'll always be where injustice is in spirit. All throughout The Grapes of Wrath, they talk about a silent army that no one knows about, the revolution that is ahead of them because of the injustices that are being served towards the Okies...and Tom saying this speech shows that he understands and realizes what is to come...and he promises that he or someone like him will always be there to resist this kind of oppression.
