The horrific attack on a

has shocked the world. Twelve people, including the newspaper's editor, are dead in France's deadliest postwar terror attack.

The gunman presumably targeted the newspaper, known as Charlie Hebdo, for its satirical cartoons that have been criticized by Muslims as being heretical. It wasn't the first time the weekly paper has been under attack, having been firebombed in 2011.

Meanwhile, France has raised its security alert to the highest level.

The attacks have raised concerns about security in the U.S. As recently as October, military personnel and civilians working for the Pentagon were told to scrub identifying information sent out over social media following concerns it could be used by Islamic militants. In the same month, the FBI warned U.S. news organizations they could be the target of terrorist attacks.

That brings us to our comment of the day. It's from a commenter known as "The Stig," and touches on fears of terrorism and how an armed citizenry might help prevent such attacks.

Stig said "It is only a matter of time until similar incidents occur in America. Yet another good reason that both our police and our citizenry are armed."
