Are Mississippi public schools authorized to deny access to a particular member of the print / television / radio media to cover school sporting events while allowing other members to cover such events, and may conditions or fees be imposed on media by the school for covering such events? May a cablevision sports programmer who tapes a complete public school event for broadcast at a subsequent time for profit, be charged a fee by the public school, while print and television station media are allowed to report the event without paying such a fee?
