Cover art for John Law lyrics by Dropkick Murphys

Suburban Anarchists who've never broke the law Sing about police oppression, but they've never met John Law

That pretty much sums up the whole song for me. This song is not only about the cops who are never heard about doing their duty, but about the people who slam them because of blind beliefs they have police. Too many people see them as extensions of a state they don't approve of, and not ordinary guys trying to keep their neighborhoods safe to live in. It's nice to see this kind of sentiment in music nowadays, especially from a punk band (a rarity indeed).
