Iterated Confirmation Bias

When an individual is accused to be violent, his subsequent actions would be judged as malicious. Because his first impression was a violent individual, people distort evidence to confirm to that first impression. For example, his actions which are perceived to be as violent would be emphasized, and his actions which are perceived not to be violent would be ignored. Thus, it is ideal for people who are accused of violent crimes to be presumed innocent, and have a fair trial, to avoid the "iterated confirmation bias effect."
