Update: When news broke that a 14-year old student had been shot at an Atlanta middle school on the morning of Jan. 31, reports did not mention that the shooter had been disarmed by an armed guard at the school. But Atlanta Police Chief George Turner is now saying the shooter was in fact disarmed by an armed guard working at the school.  

In other words, today's shooting proves the point the NRA has been emphasizing since Sandy Hook Elementary--"The only way to stop a bad guy with a gun is a good guy with a gun."

What is now known is that the shooter was another student, who is in custody, and the victim was a male student who was shot in the neck. The injuries did not appear to be life-threatening, and the victim was alert and conscious when medical personnel arrived on the scene.

Unlike shootings in other "gun free zones"--this scope of this shooting was greatly diminished because an armed guard was in the school. Can we learn a lesson from this? 

NOTE: This article originally described the shooting victim as a female, which later news reports have contradicted.
