"Improvised explosive device (IED) attacks remain the primary tactic for terrorists seeking a relatively uncomplicated, inexpensive means for inflicting mass casualties and maximum damage. There is a growing concern in the law enforcement and homeland security community about the availability of precursor chemicals and materials that can be purchased legally or potentially stolen from commercial businesses. Once obtained, these materials can be used to create homemade explosives (HME) and a variety of IEDs for multiple purposes, including carrying out a terrorist attack. The United States Department of Homeland Security, Office for Bombing Prevention (DHS/OBP) is sponsoring a new outreach program known as the Bomb-Making Materials Awareness Program (BMAP). BMAP aims to increase private sector awareness of activities associated with bomb-making, including the manufacture of HME, common explosives used in terrorist IEDs. Our Department and your local police department would like to encourage your business to participate in this important initiative. The private sector has a significant role in helping to prevent IED attacks. It is imperative that the private sector recognize suspicious behavior and purchases that may be indicative of bomb-making activity. Bomb-making steps are generally the same regardless of an individual's appearance or ideological/religious affiliationEffective practices in identifying suspicious behavior and purchases include both paying attention to customers and knowing what is suspicious."
