On the Accuracy of the Threat Level Detection

I'm sure that you all were absolutely horrified at first when the hostage in the first episode was given a lethal threat rating by Dominator, as was I. But as she doused the floor in gasoline and was about to kill everyone around her with a lighter, I was afraid to admit that the Dominator was accurate. The enforcer who was about to kill her would have been right to do so. Sure, she was managed to be talked out of it, but in a life-or-death scenario, it's not always feasible to take those kinds of chances. I begrudgingly found myself at least partially trustworthy of the Dominator's rating. At first, I thought that Akane would be punished a lot more harshly than she was for how she handled the situation with the female hostage. But even though Shinya was the enforcer who was about to pull the trigger, her recognized and agreed with Akane's humanity.  Ginzo has this whole business of learning through history rather than experience. Is a part of him right? Are Dominators usually correct and are Enforcers always quick to pull the trigger out of their own safety? Personally, I think it speaks to a larger theme of police bruality in Psycho-Pass and how it's brushed over because it's the system that takes responsibility for the actions of law enforcement. Akane doesn't seem to have to do much of anything other than watch the Enforcers, and the Enforcers only have to do what the system tells them to do.

There are a lot of factors that I think the threat detection system doesn't consider. This isn't a utopia that tries to be perfect (see the drone murders in the factory). The admitted holes see to rely on logic not being equatable to illogical human behavior and the ability of a threat level to change with reasoning.
