The police lied
Remember Navtej Singh. He was killed in his Manurewa liquor store and police said that the 30 minute delay in getting in to the store was merely procedural.
Police with access to the weapons cache required to secure the scene took the wrong set of keys to unlock it and were forced to wait for an officer to get the correct keys from the police station. That caused the delay, but the police didn't want to tell you that. Furthermore another officer thought it was better to take a colleague to the police station with an offender before attending the fatal shooting.
Bloody outrage, the Sunday News screams. Damned right it is.
