The media basically understands very little about the autism spectrum, but that "very little" is much more than they know about personality disorders. Heck, the common person does not understand much, if anything, about personality disorders. Watch the television, and you'll see stories about multiple personality disorder - something that has no mental health backing and even its closest relative (disassociative personality disorder) removed from the DSM-V, but most people you ask would state that someone in a mental hospital very possibly may have multiple personality disorder. Obsessive compulsive disorder is in the grouping of personality disorders, but it is far different than borderline personality disorder, so there is a wide array of things to know in the area, and believe me when I say the media knows NONE of it. In fact, if they did, there would actually be something to latch onto and "blame" depending on if it was ever diagnosed within the personality disorder family - antisocial personality disorder, whose sufferers typically will commit numerous petty crimes as an essential "need" to fight against rules of society, and a person with this disorder can actually be driven in anger to the point of lashing out physically and violently.
