No. The real sick is that the French government doesn't allow people to keep guns with them. If the government could protect the people, it might be okay, somewhat. But the government can't protect the people, as evidenced by this.
If the magazine people had guns with fully loaded "magazines" with them at their desks, they would have been able to fend off the crooks. Possibly the crooks would never have done the thing they did, knowing that the people would fight back WITH GUNS.
Crooks are free to own guns (well, they obviously were in this case). Why not the good people?
Let the law abiding people own all kinds of armament so that they can protect themselves and the police who attempt to protect them.
When the gunmen are found, and when it is proven that they are for sure the murders, execute them.
