Even with its post-9/11 national security responsibilities, the FBI continues to play a key role in combating violent crime in big cities and local communities across the United States.
The Bureau concentrates on crime problems that pose major threats to American society. Significant violent crime incidents such as mass killings, sniper murders, and serial killings can paralyze entire communities and stretch state and local law enforcement resources to their limits. Particular emphasis is put on criminal street gangs, bank robberies, carjackings, kidnappings, interstate transportation of stolen property and motor vehicles, assaults and threats of assault on the president and other federal officials, and the theft or destruction of government property. As part of this priority, the FBI also investigates crimes against children, art theft, child prostitution, fugitives and missing persons, and crimes on Indian reservations.
