Since the September 11, 2001 attacks, governments in many countries have stepped up efforts to protect their citizens and employees from all types of terrorist threats. The number of mass shootings has dramatically increased in recent years, particularly in the United States, as has the frequency of bombings and suicide attacks worldwide. High-traffic areas and large gatherings are usually targeted: airports, stadiums, shopping malls, schools, concert halls, government buildings, etc. However, the terrorist threat is not limited to physical locations.
