The Second Amendment? What Second Amendment?

The principal of a Georgia elementary school might need to brush up on her U.S. Constitution knowledge after banning a parent from volunteering in the classroom because the mom posted a photo of her concealed carry permit on Facebook.

Tanya Mount, an Army veteran and mom of a student at McBean Elementary School, received a criminal trespass warning statement from the Richmond County Board of Education police on Oct. 23, according to the local CBS News affiliate.

"I feel like a criminal," Mount told WRDW. "I want -- I want to be heard. I want a public -- I want a public apology."

In response to being issued the warning and banned from the school, Mount inquired about what she apparently did wrong.

"And he [the officer] asks, 'Were you in the Army?' and I said yes. He's like, 'Do you have a concealed weapons permit?' I said yes," Mount told WRDW.

Principal Janina Dallas confirmed to the local ABC News channel WJBF that the warning was issued in response to Mount's firearms permit.

"It is my duty and responsibility as the principal of this school to ensure the safety and security of all of our faculty, staff and students," she told the station.

Dallas defended the ban on Mount by pointing out that members of the school's parent-teacher organization observed that the mom would disrupt class or not allow anyone near her daughter. The principal suggested those could be warning signs if coupled with a handgun permit. Mount responded by saying if the principal is that concerned about the safety of students, the ban should be extended to all parents with firearms, not just her.

Mount posted on her Facebook last week that her daughter will now be attending another school, an option presented to her by the school district. And on Tuesday, Mount lashed out on her page in response to apparent criticism over posting a photo of her permit online.

"... I am a private person, however after serving OUR country, it is my DUTY to make sure that our lives are not infringed upon, however do it all within the confinements of the LAW..." she wrote.
