No if's, no buts. He was cool as a cucumber. He has done this before. The way he would reload - step back in the narrow hallway so there was less chance of being jumped as he reloaded.
He is totally confident.
The video is very disturbing, especially the young Muslim woman on the ground in front of the Mosque whimpering "Help me! Help me!" He blew the top of her head off.
You do not handle an AR15, military-style semi-automatic assault rifle like that unless you have trained to clear jams and misfires in the efficient manner he displays. He darts back into cover, out of the expansive prayer hall into a narrow hallway to change magazines - this is not something you do naturally. This is military training. House clearing - to make it harder to be attacked while changing magazines.
It is impossible to obtain an AR15 style assault rifle in Australia. Even a well connected organised crime figure would have trouble and you would immediately risk being on the "police radar" if you tried. So where did he train in their operation, tactics and handling? He was not long in New Zealand. He cannot buy firearms in New Zealand as an Australian citizen. Who brought them for him? Who supplied them? It is legal to own the AR15 he used and semi-automatic shotguns with the appropriate hunting licenses. Some claim his AR15 magazines were illegal 30 round.
In the dock, he looks 5ft 4inches. Muscular. He looks special forces - small and powerful. How they like them. Travelled extensively. Especially in Europe. Claimed he was a simple working class lad - made his money investing in crypto, ie: he's a drug dealer. Absolutely he is. I knew a guy who worked security in Palestine when Arafat had casinos. He had no military training. He learned on the job. That's where I think that guy has come from. They claim he was in Pakistan, who knows. I just know what I saw in that video.
