A very unfortunate story; the judge is in family court, incidentally, and I've heard it said that family court is the place in the court system where violence (usually by disgruntled litigants) is most likely. My best wishes to the judge, who seems very seriously wounded but still alive, and to his family.
This event is obviously a tragedy to those involved, but attempted murders of judges, even more than attempted murders of ordinary citizens, are especially troubling because they threaten our justice system as well as individual victims; I thus thought this incident was particularly noteworthy. Thanks to How Appealing for the pointer.
UPDATE: The judge's administrative assistant was apparently also hit, though her injuries seem to have been less serious.
