NSW Police conference 1 hour ago
There were 6 firearms used in the shooting. The 50-year-old father is a licensed firearms owner (the person who was disarmed), and there is no reason to suspect that there were a third person was involved.
My honest take on the shooting.
The duo planned the shooting; they knew the event, they knew the bridge is overlooking the event, they were using a spare weapon layout on that bridge, and they were also using a drop leg bag for ammo storage.
But as far as I'm concerned, these people aren't trained seriously. Maybe there are more relations with any terrorist group, but I doubt they had any external training.
