You fail to understand the point. Whatever the specific case is, your argument is that "it's her fault because she did not exercised prudence", and the counter-argument is "in Justice, what you say is simply not true".
And again, your argument is illogical: you can say exactly the same about the ICE agent (they did not acted carefully enough). Why is the victim guilty of not have considered the aggressor as unhinged, and the aggressor not guilty of avoiding the situation that they use to justify their behavior.
<< Why is the victim guilty of not have considered the aggressor as unhinged, and the aggressor not guilty of avoiding the situation that they use to justify their behavior.
Because the 'aggressor' is not aggressor, but a governmental employee mandated to be violent when necessary AND we do have a verb ( and corresponding crime ) for people who choose to stand in the way of such an employee: obstruction of justice ( edit: replaced duty -- other thread was on my mind ).
Your whole world is mildly warped, because you think you can simply apply victim/perpetrator filter to make the whole concept somehow flip. But reality does not work that way.
