Within hours of a scissors-wielding man being shot dead by police at Central Station on Wednesday night, the force issued the type of statement we have come to associate with what it clinically refers to as "critical incidents". The statement said that the homicide squad would "now investigate all circumstances surrounding the incident".

"That investigation will be subject to independent review and all information will be provided to the Coroner," it said.

It's early days and the details of the shooting – which reportedly saw up to four shots fired – are yet to be fully understood.

The man - Danukul Mokmool - appeared highly distressed and possibly mentally ill, but again this is pure speculation based on grainy bystander video.
