Mr Cregan denies killing PCs Nicola Hughes, 23, and Fiona Bone, 32, in Hattersley, Greater Manchester last September. He also denies the murders of David Short, 46, and his son, Mark, 23... Mr Cregan appeared in court wearing a false left eye made of black onyx.
Mr Nicholas Clarke QC, prosecuting, said PCs Hughes and Bone were killed as they responded to a report of a burglary on the morning of 18 September.
Mr Clarke said: "[Cregan] lay in wait with a Glock firearm with an extended magazine that was fully loaded.
"PC Fiona Bone and PC Nicola Hughes attended. As soon as they arrived Cregan, who was on the run, shot the officers repeatedly, until his magazine was empty.
"As he left the scene he again threw a grenade towards the victims."
The ludicrous, clownish hack Piers Morgan hardest hit.
