According to local reporting in Tucson, Congresswoman Giffords is not dead but is in surgery. AzTheta tells me that a local news channel is still reporting that she is alive in surgery. Is NPR and CNN prematurely reporting her death? Weird. Could be she is in surgery as an organ donor. I don't know, but it's awfully confusing with the conflicting reports (I have no links since these are tv reports.) NPR and CNN links are sketchy.
