The Bomb Arson Tracking System (BATS) is a web-based case management system which provides you, State and local arson & explosives investigators, access to up-to-date arson and explosives investigative data from across the nation. Unlike anything you may currently use, it's not just limited to your local jurisdiction or state. BATS provides you access to national arson and explosives incident information.
