I found this in Flint's ordinances...
§ 31-20 FIREARMS— HANDLING, FIRING AND THE LIKE.
The word FIREARM
except as otherwise specifically defined in this code, shall be construed to include any weapon from which a dangerous projectile may be propelled by using explosives, gas or air as a means of propulsion.
(b) It shall be unlawful for any person, except an officer in the discharge of his duties, to draw, flourish or fire any firearm in the City, except as authorized by law; provided, that nothing contained herein shall prohibit the drawing, flourishing or firing of air guns or firearms in duly licensed firing ranges or shooting galleries.
(c) It shall be unlawful for any person to transport or to have in possession in or upon any vehicle a firearm unless the same is unloaded in both barrel and magazine and carried in the luggage compartment of the vehicle. It shall be unlawful to carry a firearm on any public street or in any public place unless it is unloaded and in a case, except as authorized by law.
(d) Any person observed doing any of those things prohibited by this section shall be required to represent to any peace officer, forthwith, evidence of authorization that the person is exempt from the provisions thereof.
This wouls seem to prohibit open carry in the city of Flint. Might be relevant considering your proposed gathering in Flint next Sat.
Is this a case where the preemption clause would prohibit Flint from enforcing that ordinance?
Every Flint cop I've talked to says open carry is illegal. Maybe this is why they think that way.
