An Oregon high school teacher is suing for the right to bring her gun to work. The unnamed plaintiff, “Jane Doe” in court filings, obtained a concealed weapon permit several years ago as protection against her abusive ex-husband, but says that campus shootings such as that at Virginia Tech in April have convinced her that she needs her gun in the classroom, in case some crazed student goes on a rampage. “I have two children in school,” says Doe, “and I would like to think that if something like that ever happened, there would be somebody there to do the right thing to protect my kids.”
