Mississippi Code Annotated section 97-35-7 is the statute that prohibits "disorderly conduct." It sounds like it was written as a reaction to civil rights protests. In any event, it says:
(1) Whoever, with intent to provoke a breach of the peace, or under such circumstances as may lead to a breach of the peace, or which may cause or occasion a breach of the peace, fails or refuses to promptly comply with or obey a request, command, or order of a law enforcement officer, having the authority to then and there arrest any person for a violation of the law, to:
(a) [go away], or
(b) [get up and move], or
(c) [stop lying down or sitting somewhere], or
(d) [get out of the way of a car], or
(e) [basically the same thing as (d)], or
(f) [untie himself from something or someone], or
(g) [basically the same thing as (f)], or
(h) [get in a police car], or
(i) [do something or stop doing something] as ordered, requested or commanded by said officer to avoid any breach of the peace at or near the place of issuance of such order, request or command, shall be guilty of disorderly conduct, which is made a misdemeanor and, upon conviction thereof, such person...shall be punished by a fine of not more than Five Hundred Dollars ($500.00) or imprisonment in the county jail for not more than six (6) months, or by both such fine and imprisonment.
