What is the FBI’s responsibility in bombing cases?

The FBI investigates the malicious damaging or destruction, by means of an explosive, of property used in interstate or foreign commerce. These matters include the bombing or attempted bombing of college or university facilities and incidents that appear to have been perpetrated by terrorist or revolutionary groups. The FBI also investigates bombings in the U.S. and overseas where incidents were acts of terrorism against U.S. persons or interests. Bombings are also under the ATF jurisdiction, so there are often collaborative investigations of large-scale incidents. The FBI collects evidence, interviews witnesses, develops leads, and identifies and apprehends the person or persons responsible. The FBI also assists U.S. Attorneys in preparing evidence or exhibits for trial.
