The Attorney General
is authorized to inspect the site of any accident, or fire, in which there is reason to believe that explosive materials
were involved, in order that if any such incident has been brought about by accidental means, precautions may be taken to prevent similar accidents from occurring. In order to carry out the purpose of this subsection, the Attorney General
is authorized to enter into or upon any property where explosive materials
have been used, are suspected of having been used, or have been found in an otherwise unauthorized location. Nothing in this chapter shall be construed as modifying or otherwise affecting in any way the investigative authority of any other Federal agency.
In addition to any other investigatory authority they have with respect to violations of provisions of this chapter, the Federal Bureau of Investigation
, together with the Bureau of Alcohol, Tobacco, Firearms, and Explosives,
shall have authority to conduct investigations with respect to violations of subsection (d), (e), (f), (g), (h), or (i) of section 844 of this title
