(Newser) – A social studies teacher from Maine was arrested on domestic violence charges last month—while wearing a "Stop Domestic Violence" T-shirt, the Bangor Daily News reports. Jezebel refers to this as the "bad kind of irony." Police say 38-year-old Emily Wilson was arguing with her husband in their bedroom—she believed he was having an affair—when she waved a gun around before firing it into their mattress. She also allegedly grabbed her husband's wrist. According to the Smoking Gun, Wilson's husband called 911 and she was arrested. She's been charged with domestic violence, reckless conduct with a dangerous weapon, and domestic violence assault. She faces up to five years in prison and a $5,000 fine. Should have listened to the shirt. (Read more weird crimes stories.)
