18 U.S. Code § 37 - Violence at international airports
(a) Offense.— A person who unlawfully and intentionally, using any device, substance, or weapon—
(1) performs an act of violence against a person at an airport serving international civil aviation that causes or is likely to cause serious bodily injury (as defined in section 1365 of this title) or death; or
(2) destroys or seriously damages the facilities of an airport serving international civil aviation or a civil aircraft not in service located thereon or disrupts the services of the airport,
if such an act endangers or is likely to endanger safety at that airport, or attempts or conspires to do such an act, shall be fined under this title, imprisoned not more than 20 years, or both; and if the death of any person results from conduct prohibited by this subsection, shall be punished by death or imprisoned for any term of years or for life.
(b) Jurisdiction.— There is jurisdiction over the prohibited activity in subsection (a) if—
(c) Bar to Prosecution.— It is a bar to Federal prosecution under subsection (a) for conduct that occurred within the United States that the conduct involved was during or in relation to a labor dispute, and such conduct is prohibited as a felony under the law of the State in which it was committed. For purposes of this section, the term “labor dispute” has the meaning set forth in section 2(c)  of the Norris-LaGuardia Act, as amended (29 U.S.C. 113 (c)), and the term “State” means a State of the United States, the District of Columbia, and any commonwealth, territory, or possession of the United States.
 So in original. Probably should be section “13(c)”.
