The Critical Incident Response Group of the FBI consists of multiple departments which provide logistical, event, information systems, profiling and multi-agency coordination support. Together, these make up he Investigations and Operations Support Section (IOSS).

The services provided by IOSS are essential to the FBI’s performance. Without the IOSS, the FBI’s activities that protect national security at home and abroad would not be possible.

To protect the U.S. and U.S. interests from terrorist attacks, the FBI needs these many programs. For instance, The Behavioral Analysis Unit gives inimitable insight into the psychology of criminals and terrorists in order to anticipate violent crimes. Similarly, the FBI is able to protect major events including sports, conferences and political gatherings from threats, by employing the Special Events Management Unit. And when the FBI needs to travel, it uses the Rapid Deployment Logistics Unit to set up remote command points.

These extensive resources are how the DBI successfully investigates, solves, and stops crimes. The National Center for Analysis of Violent Crime uses historical information as well as up-to-the-minute research to understand the nature of violent criminals and preempt and stop their potential offences. Law enforcement programs carried out at federal, state, local and international levels are coordinated by The Violent Criminal Apprehension Program. The Critical Incident Response Group is supported by the Communications and Information Technology Unit, which helps with technology and IT.

The National Center for Analysis of Violent Crime

The three Behavioral Analysis Units and the Violent Criminal Apprehension Program fall within the The National Center for Analysis of Violent Crime (NCAVC). This was created in 1984 in furtherance of the investigation of crimes like murder, serial rape, explosives based violence, terrorism, extortion and child offences. Using existing databases and new studies into psychology, NCAVC is able to assist and advise FBI Special Agents in the solving and preventing of crimes.

Behavioral Analysis Unit


The Behavioral Analysis Unit is managed by NCAVC, and has three sections. They are:

1. BAU-Counterterrorism/Threat Assessment
2. BAU-Crimes Against Children
3. BAU-Crimes Against Adults

The Behavioral Analysis Units give information to support missions where time is of the essence. These include cases including ones where serial killers are at large, or armed fugitives are on the loose. The Behavioral Analysis Unit undertakes psychological assessments known as “profiling”. Cases involving arson, explosives, stalking and national security normally fall to the Counterterrorism unit. The The Crimes Against Children Unit undertakes murder, kidnapping and other disappearances and exploitation of children, while The Crimes Against Adults unit undertakes these crimes that are related to adults, also including white-collar, organised crime, and civil rights.

The Violent Criminal Apprehension Program is the fourth arm of NCAVC. Operating the largest database of violent crimes in the U.S. is ViCAP Web, which various law enforcement agencies around the country have authorisation to access. The ViCAP includes over 84,000 cases gathered together from 4,000 police agencies. This means that ViCAP is often the lead agency when multiple law enforcement bodies are working together to solve a crime. ViCAP has many investigative and psychological methods for solving crimes, including catching fugitives, missing persons and unidentified bodies

Communication and Information Technology Unit

Extensive information and telecommunications system are essential for the FBI to carry out its business. The Communications and Information Technology Unit is responsible for developing, implementing and managing the communications systems needed by the FBI. CITU must be constantly vigilant and fast moving in upgrading their technology so that the FBI has the most up to dat crime solving resources at their behest.

Special Events Management Unit

The FBI is charged with protecting major events from political summits to the Super Bowl from terrorist and cyber attacks, riots and other violent criminal activity. This is why the Special Events Management Unit was put together. The FBI considered past events and their profiles, including the Atlanta Olympics bombings and the Munich attacks in order to develop better strategies for not only FBI professionals, but other law enforcement staff and private security professionals. SEMU oversees traffic, aircraft diversions and security training around these events.
