When someone describes a fantasy about bashing a co-worker's skull in with a baseball bat they are giving us an important clue about their own psyche. A cursory look around the internet reveals such things as "Telling others about violent thoughts or fantasies" is a warning sign for workplace violence.
Similarly elsewhere we learn that "discussions of an attack, threatening co-workers or the boss" are warning signs of workplace violence.
So when Obama appointee Sonya Sotomayor fantasizes about attacking Justice Antonin Scalia with a baseball bat we shouldn't be too dismissive of it. She's broadcasting a violent tendency loud and clear.
Let's hope she can keep that hot temper under control. She'll take it out on litigants in the cases she hears. We're pretty much stuck with that. But we should all hope she doesn't take a bat to someone with whom she disagrees. And her co-workers should keep a wary eye on her but not let the fear of violent behavior influence their opinions.
