Two men now charged with a murder in Hueytown. The suspects are identified as Romel Cunningham and Kamal Potts. Police say they shot and killed 66-year old Howard McKee, a retired Birmingham fireman and Vietnam veteran.  Investigators say the murder happened after the men broke into McKee's home.  "They're not just a danger to any one person, they're a danger to us all," said deputy district attorney Bill Veitch. "They wouldn't hesitate to shoot you."    Hueytown Police Chief Chuck Hagler called the murder an outrage.
