The first thing they should have caught was him speeding through the street on the north side of downtown. Post 911, there isn't an excuse for complacency. Everyone who gets on a plane since knows it. G?uaranteed Christchurch has tactical, and however funded, they know their job, and should have been immediately deployed in such a peaceful country when a "shots fired" call came in. It was lazy and incompetent across the board. Probably Chicago PD are far more incompetent in most ways, but that was an abysmal response time, having nothing to do with their funding. Funding more rollers wouldn't have helped a single thing, IMO.
