If someone accused you of an evil actions over a decade ago without giving an exact time or location how could how defend yourself? You might try to show that there is nothing in your records to demonstrate any propensity for such an evil act but is that enough to convince those who are bent in a different direction? Maybe the person who has made this accusation doesn’t have the cleanest record themselves or has shown a disdain for people such as you in the not to distant past, would that be enough to convince those who stand in their camp? I’m afraid not for some don’t want to look at the facts on the ground but rather stand in a camp that they feel more comfortable with.
