Final answer:
The FBI Active Shooter Report from 2014 excludes gang-related and drug-related shootings, as well as other incidents without the potential for mass harm, focusing instead on active shooter events that pose a threat to the public.
Step-by-step explanation:
The FBI Active Shooter Report from 2014 is a document detailing incidents of active shootings in various environments. However, it excluded certain types of shootings due to their methodology of classifying an active shooter situation. They typically do not include instances such as gang-related shootings, drug-related shootings, or incidents that did not involve the potential for mass harm, such as a firearm discharged within a family dispute that did not extend to the wider public or a broader threat. The inclusion criteria for the report focus on cases where individuals were actively engaged in killing or attempting to kill people in populated areas. Also, the report does not cover other forms of violence or crime statistics such as the lowest level of law enforcement fatalities or single-bias incidents, like those related to hate in 2015.
