(2) Members may communicate overtly with the organizers of a First Amendment assembly concerning the number of persons expected to participate, the activities anticipated, and other similar information regarding the time, place, and manner of the assembly.
(3) Members may communicate overtly with persons other than the organizers of a First Amendment assembly to obtain information relating to the number of persons expected to participate in the assembly.
(4) Members may collect information on prior First Amendment assemblies to determine what police resources may be necessary to adequately protect participants, bystanders, and the general public, and to enforce all applicable laws.
(b) Filming and photographing First Amendment assemblies may be conducted by MPD members for the purpose of documenting violations of law and police actions, as an aid to future coordination and deployment of police units, and for training purposes.
