They ARE weasel-words. Nothing foolish about it. Modern society does NOT have an effective method of preventing sociopaths from doing harm again. They "could" have, but they don't. There are at least two possibilities--permanent incarceration in solitary confinement, or surgically severing the spine so the sociopath has no use of arms or legs. In both cases, the individual can still repent and save his soul.
"Rarely" is not "never".
If memory serves, that was a common turn-of-phrase directed at JPII when he warned us of the Iraq misadventure. Right now, his words appear prophetic. Let me know when you (or anyone who's currently trumpeting Iraqi liberation) are planning a move to or even a vacation in Baghdad.
Saddam is yesterday's news. Irrelevant. Totally and utterly. He is a total non-factor in the jihad against America and the wider Islamic resurgence.
In fact, I'll go even further. His execution will aggravate the present Iraqi anarchy.
