A federal grand jury has indicted the company W.R. Grace and seven of its executives for failing to warn the residents of Libby Montana about the dangers of a cancer-causing asbestos mine in their town. The executives are accused of trying to hide the danger from workers and townspeople. Studies have shown that nearly 200 died and more than 1200 became ill because of exposure to asbestos. The indictment was unsealed less than a week after President Bush described lawsuits by victims of asbestos against companies such as WR Grace as “frivolous.”
