"I was going to send it to my husband to show what our mischievous little three-year-old was up to," Stacey Feeley wrote on Facebook. "However, the moment she told me what she was doing, I broke down. She was practicing for a lockdown drill at her preschool and what you should do if you are stuck in a bathroom. At that moment, all innocence of what I thought my three-year-old possessed was gone."
She posted the photo of her daughter on Facebook, urging politicians to "take a look."
