There Ought To Be A Law - a new film that follows Cathy Crowley of Lewiston, Maine in the months after her 18-year-old son bought a shotgun at Wal-Mart and killed himself. Crowley felt compelled to talk to the salesperson who sold him the weapon. The Wal-Mart manager told her that the store was following the law and if she didn't like it, she should try to change it. So Crowley decided to do just that. She had no political experience, and had never even voted. But she sat at her kitchen table for 10 hours and wrote to every single lawmaker in the state legislative directory. Several lawmakers agreed to sponsor a bill that would require a waiting period before young people could buy guns.
