Uncertainty and Plausible Deniability

Plausible deniability is a key strategy in keeping secrets. It is when an authority figure has the ability to keep their "distance" from a circumstance or situation they were the initiators of and bore indirect or even direct responsibility for, but because they separated themselves from it in terms of paperwork and physical traces, evidence for their participation in a crime or ethical violation can be denied. 

This is absolutely because of human awareness limitations and the inability to sort through uncertainty. 

Uncertainty naturally comes out of a lack of awareness or record, but truth remains true and physical and information evidence of a wrongdoing exists even if the crime or violation is covered up.

         This is because you can't destroy energy, and you can't essentially destroy information, even if you break it into pieces, conceal it, or alter it.

       The information still exists. It's just up to humans as receivers of information with limited fields of awareness to seek the truth and sort through the scattered, broken pieces of information and evidence when we are trying to solve problems.

    Plausible deniability is an excellent way for a government or individual to absolve themselves of guilt or responsibility for wrongdoings and avoid being held accountable, but there is always evidence. Between physical and written evidence and or even the memory of victims of some of these crimes and violations, evidence still remains. Truth still remains.
