Search 42 U.S.C. § 2000aa : US Code - Section 2000AA: Searches and seizures by government officers and employees in connection with investigation or prosecution of criminal offenses

    (a) Work product materials
      Notwithstanding any other law, it shall be unlawful for a
    government officer or employee, in connection with the
    investigation or prosecution of a criminal offense, to search for
    or seize any work product materials possessed by a person
    reasonably believed to have a purpose to disseminate to the public
    a newspaper, book, broadcast, or other similar form of public
    communication, in or affecting interstate or foreign commerce; but
    this provision shall not impair or affect the ability of any
    government officer or employee, pursuant to otherwise applicable
    law, to search for or seize such materials, if - 
        (1) there is probable cause to believe that the person
      possessing such materials has committed or is committing the
      criminal offense to which the materials relate: Provided,
      however, That a government officer or employee may not search for
      or seize such materials under the provisions of this paragraph if
      the offense to which the materials relate consists of the
      receipt, possession, communication, or withholding of such
      materials or the information contained therein (but such a search
      or seizure may be conducted under the provisions of this
      paragraph if the offense consists of the receipt, possession, or
      communication of information relating to the national defense,
      classified information, or restricted data under the provisions
      of section 793, 794, 797, or 798 of title 18, or section 2274,
      2275, or 2277 of this title, or section 783 of title 50, or if
      the offense involves the production, possession, receipt,
      mailing, sale, distribution, shipment, or transportation of child
      pornography, the sexual exploitation of children, or the sale or
      purchase of children under section 2251, 2251A, 2252, or 2252A of
      title 18); or
        (2) there is reason to believe that the immediate seizure of
      such materials is necessary to prevent the death of, or serious
      bodily injury to, a human being.
    (b) Other documents
      Notwithstanding any other law, it shall be unlawful for a
    government officer or employee, in connection with the
    investigation or prosecution of a criminal offense, to search for
    or seize documentary materials, other than work product materials,
    possessed by a person in connection with a purpose to disseminate
    to the public a newspaper, book, broadcast, or other similar form
    of public communication, in or affecting interstate or foreign
    commerce; but this provision shall not impair or affect the ability
    of any government officer or employee, pursuant to otherwise
    applicable law, to search for or seize such materials, if - 
        (1) there is probable cause to believe that the person
      possessing such materials has committed or is committing the
      criminal offense to which the materials relate: Provided,
      however, That a government officer or employee may not search for
      or seize such materials under the provisions of this paragraph if
      the offense to which the materials relate consists of the
      receipt, possession, communication, or withholding of such
      materials or the information contained therein (but such a search
      or seizure may be conducted under the provisions of this
      paragraph if the offense consists of the receipt, possession, or
      communication of information relating to the national defense,
      classified information, or restricted data under the provisions
      of section 793, 794, 797, or 798 of title 18, or section 2274,
      2275, or 2277 of this title, or section 783 of title 50, or if
      the offense involves the production, possession, receipt,
      mailing, sale, distribution, shipment, or transportation of child
      pornography, the sexual exploitation of children, or the sale or
      purchase of children under section 2251, 2251A, 2252, or 2252A of
      title 18);
        (2) there is reason to believe that the immediate seizure of
      such materials is necessary to prevent the death of, or serious
      bodily injury to, a human being;
        (3) there is reason to believe that the giving of notice
      pursuant to a subpena duces tecum would result in the
      destruction, alteration, or concealment of such materials; or
        (4) such materials have not been produced in response to a
      court order directing compliance with a subpena duces tecum, and -
       
          (A) all appellate remedies have been exhausted; or
          (B) there is reason to believe that the delay in an
        investigation or trial occasioned by further proceedings
        relating to the subpena would threaten the interests of
        justice.
    (c) Objections to court ordered subpoenas; affidavits
      In the event a search warrant is sought pursuant to paragraph
    (4)(B) of subsection (b) of this section, the person possessing the
    materials shall be afforded adequate opportunity to submit an
    affidavit setting forth the basis for any contention that the
    materials sought are not subject to seizure.
