Try'n to behave
Mayor Chokwe Antar Lumumba (D-MS) issued an order temporarily prohibiting law-abiding citizens from open carry during the coronavirus crisis.www.breitbart.com
I believe that they do.Apparently MS does not have any "pre emption" statute/law that prohibits any city/municipality/town/any government body/whoever from enacting their own rules regarding guns & ammo. Many states do have pre emption, time for MS citizens to get on their state legislators.
Mississippi has state preemption of many but not all firearm laws. No county or municipality may adopt any ordinance that restricts or requires the possession, transportation, sale, transfer or ownership of firearms or ammunition or their components. However, local governments may regulate the discharge of firearms, the carrying of firearms at a public park or public meeting, or the use of firearms in cases of insurrection, riots and natural disasters. Some counties have adopted Second Amendment sanctuary resolutions.
