This Act does not prohibit a law enforcement agency from seeking to obtain current or future location information:
         (1) to respond to a call for emergency services
    
concerning the user or possessor of an electronic device;
        (2) with the lawful consent of the owner of the
    
electronic device or person in actual or constructive possession of the item being tracked by the electronic device;
        (3) to lawfully obtain location information broadly
    
available to the general public without a court order when the location information is posted on a social networking website, or is metadata attached to images and video, or to determine the location of an Internet Protocol (IP) address through a publicly available service;
        (4) to obtain location information generated by an
    
electronic device used as a condition of release from a penal institution, as a condition of pre-trial release, probation, conditional discharge, parole, mandatory supervised release, or other sentencing order, or to monitor an individual released under the Sexually Violent Persons Commitment Act or the Sexually Dangerous Persons Act;
        (5) to aid in the location of a missing person;
         (6) in emergencies as follows:
             (A) Notwithstanding any other provisions of this
        
Act, any investigative or law enforcement officer may seek to obtain location information in an emergency situation as defined in this paragraph (6). This paragraph (6) applies only when there was no previous notice of the emergency to the investigative or law enforcement officer sufficient to obtain prior judicial approval, and the officer reasonably believes that an order permitting the obtaining of location information would issue were there prior judicial review. An emergency situation exists when:
                (i) the use of the electronic device is
            
necessary for the protection of the investigative or law enforcement officer or a person acting at the direction of law enforcement; or
                (ii) the situation involves:
                     (I) a clear and present danger of
                
imminent death or great bodily harm to persons resulting from a kidnapping or the holding of a hostage by force or the threat of the imminent use of force, or the occupation by force or the threat of the imminent use of force of any premises, place, vehicle, vessel, or aircraft;
                    (II) an abduction investigation;
                     (III) conspiratorial activities
                
characteristic of organized crime;
                    (IV) an immediate threat to national
                
security interest; or
                    (V) an ongoing attack on a computer
                
comprising a felony.
            (B) In all emergency cases, an application for an
        
order approving the previous or continuing obtaining of location information must be made within 72 hours of its commencement. In the absence of the order, or upon its denial, any continuing obtaining of location information gathering shall immediately terminate. In order to approve obtaining location information, the judge must make a determination (i) that he or she would have granted an order had the information been before the court prior to the obtaining of the location information and (ii) there was an emergency situation as defined in this paragraph (6).
            (C) In the event that an application for
        
approval under this paragraph (6) is denied, the location information obtained under this exception shall be inadmissible in accordance with Section 20 of this Act; or
        (7) to obtain location information relating to an
    
electronic device used to track a vehicle or an effect which is owned or leased by that law enforcement agency.
