A Sheboygan man will face charges after showing up at work wearing a ballistic vest, carrying a taser and several magazines full of ammunition.  Thirty-year-old Calvin Glazunov left Rockline Industries without incident when he was fired Thursday.  Later that same afternoon he returned and sat in his car while watching the building through binoculars.  Because Glazunov was known to carry an A-R-15 rifle with him, police were called.  He admitted he was there to confront his former manager about a refund for some polo shirts he had bought.  He didn’t have a gun in his possession, but he did have the taser, a baton and a flare gun.
