"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. [...] BATS is a secure, user friendly, web-based computer application. All you need is a browser and an Internet connection to use it. BATS is available to you around the clock. The BATS interface is easy to use; you enter case information into clearly identified data entry fields, and easily click dropdown menu selections. You can share your arson and explosives incidents with other BATS users across the country, and you can search and analyze national data to discover trends, patterns, and leads. You can also use BATS to create a variety of reports customized to your needs, and track and report incidents to justify budget requests."
