A bunch of hopeless suburban boys are making their usual mess around their town and I assume it's for expressing a kind of revolt over the 'social system' where they are forced to live in, since they tend to consider they are excluded from it ("I only wanted something else to do but hang around"). And the line "Break the window by the town hall" serves to show how revolted they are indeed... At the same time this same 'social system' repress their revolt with the policemen, but without considering to offer to them good opportunities for trying to conquer a better life for themselves.
