`Sec. 175. Prohibitions with respect to biological weapons

 `(a) IN GENERAL- Whoever knowingly develops, produces, stockpiles, transfers, acquires, retains, or possesses any biological agent, toxin, or delivery system for use as a weapon, or knowingly assists a foreign state or any organization to do so, shall be fined under this title or imprisoned for life or any term of years, or both. There is extraterritorial Federal jurisdiction over an offense under this section committed by or against a national of the United States.

 `(b) DEFINITION- For purposes of this section, the term `for use as a weapon' does not include the development, production, transfer, acquisition, retention, or possession of any biological agent, toxin, or delivery system for prophylactic, protective, or other peaceful purposes.

`Sec. 176. Seizure, forfeiture, and destruction

 `(a) IN GENERAL- (1) Except as provided in paragraph (2), the Attorney General may request the issuance, in the same manner as provided for a search warrant, of a warrant authorizing the seizure of any biological agent, toxin, or delivery system that--

  `(A) exists by reason of conduct prohibited under section 175 of this title; or

  `(B) is of a type or in a quantity that under the circumstances has no apparent justification for prophylactic, protective, or other peaceful purposes.

 `(2) In exigent circumstances, seizure and destruction of any biological agent, toxin, or delivery system described in subparagraphs (A) and (B) of paragraph (1) may be made upon probable cause without the necessity for a warrant.

 `(b) PROCEDURE- Property seized pursuant to subsection (a) shall be forfeited to the United States after notice to potential claimants and an opportunity for a hearing. At such hearing, the government shall bear the burden of persuasion by a preponderance of the evidence. Except as inconsistent herewith, the same procedures and provisions of law relating to a forfeiture under the customs laws shall extend to a seizure or forfeiture under this section. The Attorney General may provide for the destruction or other appropriate disposition of any biological agent, toxin, or delivery system seized and forfeited pursuant to this section.

 `(c) AFFIRMATIVE DEFENSE- It is an affirmative defense against a forfeiture under subsection (a)(1)(B) of this section that--

  `(1) such biological agent, toxin, or delivery system is for a prophylactic, protective, or other peaceful purpose; and

  `(2) such biological agent, toxin, or delivery system, is of a type and quantity reasonable for that purpose.

  `(3) the development, production, stockpiling, transferring, acquisition, retention, or possession, or the attempted development, production, stockpiling, transferring, acquisition, retention, or possession of any biological agent, toxin, or delivery system of a type or in a quantity that under the circumstances has no apparent justification for prophylactic, protective, or other peaceful purposes.

 `(b) AFFIRMATIVE DEFENSE- It is an affirmative defense against an injunction under subsection (a)(3) of this section that--
