For many, even subconsciously, attractive men are not heinous and if it's proven they are, their heinousness must've been provoked by abuse, or something somebody (i.e. wife, girlfriend, someone) did.
The Matthew Hoffman case is the one that brought me to Websleuths and I lost count on how many times his perceived attractiveness made people "surprised" at his guilt. There were theories that he must've been abused, or whatever. Even when an ex surfaced and there was proven history of DV with him.
I've seen the same with women suspects too.... like attractive people are incapable of crime. Like every murderer/monster should look the part.
