A great tragedy occurred in Tucson, Ariz., on Saturday. Six people were killed, including a 9-year-old girl, and 14 were injured, including U.S. Rep. Gabrielle Giffords, a Democrat.
The aftershock, however, has been just as tragic. At a time when the country should have been pulling together to deal with the tragedy, politics trumped civility with many on the left using this as an opportunity to take aim at their enemies on the right.
