"When law and morality contradict each other, the citizen has the cruel alternative of either losing his moral sense or losing his respect for the law." -Frederic Bastiat
"I am a conservative. Quite possibly I am on the losing side; often I think so. Yet, out of a curious perversity I had rather lose with Socrates, let us say, than win with Lenin."
― Russell Kirk, Author of The Conservative Mind
It doesn't sound like a mass shooting to me - 4 dead to include the gunman.
From now on, it seems EVERY shooting will be a sensationalized mass shooting.
If I was the Director of the FBI, I would have blood samples taken of these shooters of the last few months. Send the samples to the Center for Disease Control in Atlanta and have the laboratory screen for all known viruses. Also see if there are any unknown viruses. I know it sounds like a long shot, but you never know.
