Basically, just as the known outcome already suggests (though some people want to delude themselves with the most sensational narrative they can latch onto). Still can't be sure if that's how it really happened unless video was recorded (probably would need audio too).
Yes it's an assumption because details are under wraps whilst police get their stories straight. However I find it hard to believe a security guard would ignore police orders or do something to threaten police officers he was actively waiting for (by report he had the suspect pinned and was waiting for police)
Exactly. If he didn't want to wait for police he would have shot the suspect already. Situation defies logic.
