The 'terror' attack on New York cops that unfolded in just seconds: Smiling policemen were photographed just before hatchet-wielding Muslim radical attacked and left one of them critical

Officer Kenneth Healey, 25, and his three comrades are all smiles in a portrait taken by Dominick Williams last Thursday afternoon. Seconds later, Zale Thompson ran up to the cops - who where standing against a wall in Jamaica, Queens - and started swinging a sharp hand ax. Mr Williams says he scrambled for safety as the officers wrestled with Thompson. He hacked one of the cops in the arm before smashing Healey in the skull. The other officers opened fire, killing Thompson but also accidentally shooting and gravely wounding a bystander who was caught in the crossfire.
