Note to moderators I'm just asking people to explain reasons for the anomaly on this picture and not starting any sort of thread like the last one . This is the picture of the 4 London bombers as released by the police . can be seen on BBC web site . Would like you to look closely at the man at the rear in the white cap. Look at the bottom of his left arm. there is a horizontal bar running in front of his arm . Yet those railings appear to be behind him . Any Ideas ?
