Exactly, if proactive you get blame: if an attack had been launched at the start and one hostage killed or even just the hostage taker killed, The Project and cie would be raising hell on the absence of negotiations etc costing a life.
The family would sue and win against whoever would have acted
By not acting no responsabilities, no blame..just following orders and procedures..pathetic but this can be seen everywhere: corporate world, education, etc
A bushfire comes, you evacuate and let burn
Someone drowning/dying on a roadsid: let it go, you are not qualified->call 000 or get sued if you try to help and fail
Trained to be brainless robots, penalized by law if acting otherwise.
Not specific to Australia, probably a sign of the time for the western world.
Just have to wait for a procedure be drawn, good luck otherwise
