The US military seems like an organization where there is very little accountability given all the people they kill in training accidents, the number of procurement mishaps they have, or their continuous inability to pass an audit.

So I imagine that if the military is the guidance for how we handle this in the future, there will be paperwork, shrugs, and perhaps some performative rage when an agent commits a crime.

Responsible and accountable can be very different things. For example, see https://en.wikipedia.org/wiki/Responsibility_assignment_matr...
