(4) If the court finds that the information likely to be obtained by such installation and use is relevant to an ongoing criminal investigation and finds that there is probable cause to believe that the pen register, trap and trace device, or cell site simulator device will lead to obtaining evidence of a crime, contraband, fruits of crime, things criminally possessed, weapons, or other things by means of which a crime has been committed or reasonably appears about to be committed, or will lead to learning the location of a person who is unlawfully restrained or reasonably believed to be a witness in a criminal investigation or for whose arrest there is probable cause, the court shall enter an ex parte order authorizing the installation and use of a pen register, trap and trace device, or cell site simulator device. The order shall specify:(a)(i) In the case of a pen register or trap and trace device, the identity, if known, of the person to whom is leased or in whose name is listed the telephone line to which the pen register or trap and trace device is to be attached; or(ii) In the case of a cell site simulator device, the identity, if known, of (A) the person to whom is subscribed or in whose name is subscribed the electronic communications service utilized by the device to which the cell site simulator device is to be used and (B) the person who possesses the device to which the cell site simulator device is to be used;(b) The identity, if known, of the person who is the subject of the criminal investigation;(c)(i) In the case of a pen register or trap and trace device, the number and, if known, physical location of the telephone line to which the pen register or trap and trace device is to be attached and, in the case of a trap and trace device, the geographic limits of the trap and trace order; or(ii) In the case of a cell site simulator device: (A) The telephone number or other unique subscriber account number identifying the wire or electronic communications service account used by the device to which the cell site simulator device is to be attached or used;(B) if known, the physical location of the device to which the cell site simulator device is to be attached or used; (C) the type of device, and the communications protocols being used by the device, to which the cell site simulator device is to be attached or used;(D) the geographic area that will be covered by the cell site simulator device;(E) all categories of metadata, data, or information to be collected by the cell site simulator device from the targeted device including, but not limited to, call records and geolocation information; (F) whether or not the cell site simulator device will incidentally collect metadata, data, or information from any parties or devices not specified in the court order, and if so, what categories of information or metadata will be collected; and(G) any disruptions to access or use of a communications or internet access network that may be created by use of the device; and(d) A statement of the offense to which the information likely to be obtained by the pen register, trap and trace device, or cell site simulator device relates. The order shall direct, if the applicant has requested, the furnishing of information, facilities, and technical assistance necessary to accomplish the installation of the pen register, trap and trace device, or cell site simulator device. An order issued under this section shall authorize the installation and use of a:
(i) Pen register or a trap and trace device for a period not to exceed sixty days; and(ii) cell site simulator device for sixty days. An extension of the original order may only be granted upon: A new application for an order under subsection (3) of this section; and a showing that there is a probability that the information or items sought under this subsection are more likely to be obtained under the extension than under the original order. No extension beyond the first extension shall be granted unless: There is a showing that there is a high probability that the information or items sought under this subsection are much more likely to be obtained under the second or subsequent extension than under the original order; and there are extraordinary circumstances such as a direct and immediate danger of death or serious bodily injury to a law enforcement officer. The period of extension shall be for a period not to exceed sixty days.An order authorizing or approving the installation and use of a pen register, trap and trace device, or cell site simulator device shall direct that the order be sealed until otherwise ordered by the court and that the person owning or leasing the line to which the pen register, trap and trace device, and cell site simulator device is attached or used, or who has been ordered by the court to provide assistance to the applicant, not disclose the existence of the pen register, trap and trace device, or cell site simulator device or the existence of the investigation to the listed subscriber or to any other person, unless or until otherwise ordered by the court.
(5) Upon the presentation of an order, entered under subsection (4) of this section, by an officer of a law enforcement agency authorized to install and use a pen register under this chapter, a provider of wire or electronic communication service, landlord, custodian, or other person shall furnish such law enforcement officer forthwith all information, facilities, and technical assistance necessary to accomplish the installation of the pen register unobtrusively and with a minimum of interference with the services that the person so ordered by the court accords the party with respect to whom the installation and use is to take place, if such assistance is directed by a court order as provided in subsection (4) of this section. Upon the request of an officer of a law enforcement agency authorized to receive the results of a trap and trace device under this chapter, a provider of a wire or electronic communication service, landlord, custodian, or other person shall install such device forthwith on the appropriate line and shall furnish such law enforcement officer all additional information, facilities, and technical assistance including installation and operation of the device unobtrusively and with a minimum of interference with the services that the person so ordered by the court accords the party with respect to whom the installation and use is to take place, if such installation and assistance is directed by a court order as provided in subsection (4) of this section. Unless otherwise ordered by the court, the results of the trap and trace device shall be furnished to the officer of a law enforcement agency, designated in the court order, at reasonable intervals during regular business hours for the duration of the order.
A provider of a wire or electronic communication service, landlord, custodian, or other person who furnishes facilities or technical assistance pursuant to this subsection shall be reasonably compensated by the law enforcement agency that requests the facilities or assistance for such reasonable expenses incurred in providing such facilities and assistance.
No cause of action shall lie in any court against any provider of a wire or electronic communication service, its officers, employees, agents, or other specified persons for providing information, facilities, or assistance in accordance with the terms of a court order under this section. A good faith reliance on a court order under this section, a request pursuant to this section, a legislative authorization, or a statutory authorization is a complete defense against any civil or criminal action brought under this chapter or any other law.
