A 36-year-old man is arrested on charges of disorderly conduct after harassing women in the parking lot of an Eau Claire Walmart.  Chad Johnson is accused of blocking the path of one woman and touching her on the shoulder.  Another woman says he got into her car, demanded a ride home and wanted to take nude photos of her.  She had a concealed carry permit and she says he left when she showed him her gun.  Witnesses reported Johnson was standing in traffic a few minutes later.  Police officers who responded said he was intoxicated.
