I haven't wanted to comment on the Terri Schiavo case, because neither you nor I nor the U.S. Congress is qualified to say whether she is alive or dead. The physicians who examined her say that she is incapable of either thought or emotion, which means she is dead. The nervous system that was once part of her life may respond to various stimuli, but there is no Terri Schiavo there, no feeling, thinking person.
On the other hand, there are tens of thousands of feeling, thinking persons whose lives the U.S. Congress could protect, but won't. Ending our occupation of Iraq would save lots of them, taking decisive action in Darfur -- preferably in conjunction with other powers -- would save many more. On Congress's mindless interference in this Schiavo case and where it could lead, see the Los Angeles Times editorial, The Midnight Coup.
