Sylvia Hall of Centerfield said she decided to obtain her National Rifle Association certification, which required 45 hours of training, and teach gun-safety classes after she used her Smith & Wesson to scare off four men who showed up on her doorstep and wanted to read to her from the Bible, The (Louisville, Ky.) Courier-Journal reported Wednesday. Advertisement Hall said the men refused to take no for an answer and attempted to push their way into her home. "Women shouldn't be afraid in their own homes," Hall said. "They ought to be able to protect themselves." Hall said she now teaches gun safety to women and men in Oldham County and the surrounding areas. "A lot of times, they have not handled a gun before," Hall said of her students. The senior citizen said she would like to expand her classes to include children. "If a young person learns the correct way to shoot a gun, you're less likely to have accidents," she said.
