The Ohio National Guard has seen the enemy and it is … a school janitor who supports the Second Amendment?

The Guard’s 52nd Civil Support Team held a training drill last year in southern Ohio which pitted members against a sinister janitor and a chemistry teacher sidekick who concocted chemical weapons in two makeshift labs, unleashing them on middle school students before killing himself. Inside the lair of the creepy custodian, identified as “Mr. Wart,” agents found  “several statements about protecting Gun Rights and Second Amendment rights” on a chalkboard as well as on tables, according to the training packet.

Fortunately, none of it actually happened. Critics say it is telling that a government group’s chosen bogeyman would be Second Amendment supporters.

“They were characterizing gun owners and Second Amendment supporters as white extremists," Chad Baus, of the Buckeye Firearms Association, told FoxNews.com. "It was a month after Sandy Hook. There was a large debate where gun owners were being blamed. I think the timing of it was extremely important here.”

According to the drill, “Mr. Wart” and the unnamed chemistry teacher were producing ricin and sulfur mustard. Another clue to their motivation was a printed CNN article found among instructions for making the deadly toxins. In the article, a real story from March 2011, National Rifle Association leader Wayne LaPierre accused the Obama administration of trying to weaken the Constitution’s Second Amendment.

Other evidence found near “Mr. Wart” included the name and contact information of William Pierce, an infamous (and now dead) neo-Nazi.

The training materials were released after a request from MediaTrackers.org. After the group published the materials online earlier this month, the Guard released a statement saying the January 2013 training drill was created and run by the West Virginia National Guard.

"The exercise — one of more than 20 the team did last year — was designed to test team members' ability to respond to an unknown chemical, biological, radiological or high-yield explosive incident," the statement read. "To maximize the realism of the exercise, the Ohio National Guard wasn't involved in the creation or execution of the exercise's fictitious scenario and was deliberately not informed of its details in advance. It's not accurate to suggest that certain details of the exercise somehow reflect views or opinions of officials of the Ohio National Guard."
