A dozen soft-shoed policemen, young, like anyone’s child, gather at 640am; two, a bit older in blue fatigues, shards of silver in short haircuts, carry battering ram, riot shield, fire extinguisher and pole with noose for holding off dangerous dogs ..voices whisper.. one-who-does-nothing gives smile of authority..and off they go on wake up call … ‘doing the Lambeth Walk’ – hey!
