At risk of sounding callous, whether or not there was a violation of human rights is irrelevant to this decision. The law shouldn't be interpreted so that it hurts somebody (who might deserve it) right now. If the previous allegations were wrongly seen as unsubstantiated, then that case should be investigated separately.

However, I could see an argument for keeping criminal allegations public to allow future investigations by a concerned public. How would we balance that against possibly lifelong damage to a person's reputation?
