Guys,
You are missing the point. Guns don't kill people, Ninjas kill people and Ninjas with Guns would kill more people than ever, hence ATFs quick and limited response to the possibly armed Ninja threat in a school zone. Also, since letters from Senators from California have conclusively proved that at present the greatest threat to our border patrol agents is terrorists with .50 caliber rifles bought at US gunshows, ATF is no doubt on alert that these same terrorists might try to heighten their current terror potential by seeking to obtain both Ninja and Pirate skills via training at college campuses to whit:
"Jeremiah Ransom, a sophomore from Macon, was leaving a Wesley Foundation pirate vs. ninja event when he was detained."
So these agents where probably thinking, "Hey look there goes a Jihadi who has just completed Ninja training, he's running to a gunshow to illegallly buy a .50 Caliber rifle with which he'll be able to easily take out border agents from here. Either that or its a great excuse to practice kneeling on the neck of some young punk. That's what I call win-win. Of course, if he had some donuts that would be a trifecta."
