No end to the cruelty.

Rep. Gabby Giffords, still recuperating from traumatic brain injury after being shot in the head by a crazed gunman at a public appearance in Tucson two years ago, has been targetted again, this time in the Twittersphere over her simple and heartfelt 71-word statement at Wednesday's Congressional hearing on gun control.
