“The thing speaks for itself”
This is the legal principle that “the occurrence of an accident implies negligence.” An incident/accident proves someone was inattentive (or uncaring) earlier.
In a bureaucratic way, the professional-managerial class works to spread responsibility, which obscures blame from decision-makers and promotes negligence without consequence.
So, while the thing or event (the error) speaks loudly, accountability is smothered (in volume and quantity) by corporate and legal speak.
This dodge is itself an example of res ipsa loquitur: continued negligence is permissible, not accidental, which is the negligence of responsibility.
