Today, untold numbers of innocent people will die at the hands of another human being. It's called homicide.
A few of those people will begin the day knowing it will be their last. Hank Skinner is likely to be one of the unfortunate few. If Texas executes him today, as now seems likely, the cause of death will be recorded as "homicide."
The discomfort one feels about any of the many homicides that will occur today is related to how close one is to the victim. As I've worked uncounted hours on the Hank Skinner case these last two months, I've tried to focus on the case, not the person. There's a pragmatic but selfish reason for this. It hurts too much if you get too close.
