"NOTICE: This warrant application seeks judicial authorization for the disclosure of reverse-location information of electronic devices near a crime at or near the time of the crime. If authorized, the warrant allows law enforcement to obtain historical location information of all devices within the area described in the warrant during the specified time from entities in possession of the relevant data. The electronic devices captured in the warrant may be owned or used by both alleged criminal perpetrators and individuals not involved in the commission of a crime. For this reason, any warrant issued must require the anonymization of all devices associated with the reverse-location information."; and

(3) If a court grants a warrant under Subsection (2), the court shall require that all electronic device data provided pursuant to the warrant be anonymized before the reverse-location information is released to the law enforcement agency.
