Why are you guys the first to get your defensive mechanism in play? Seen the same thing happen when the Tucson incident occurred. A PA con was quick to quote a twittering twat said the shooter was a liberal. Would it be classier to post that another horrific incident, involving gums, had occurred?
You can defend your right to own a gun. I will not attempt to take that right away from you. However, the gun laws and regulations require modification.
