Well it may get complicated there.
Minnesota statutes about about people that can't have guns say:
MN Statute 624.713 said:
Subdivision 1.Ineligible persons. The following persons shall not be entitled to possess ammunition or a pistol or semiautomatic military-style assault weapon or, except for clause (1), any other firearm
And then it goes on to list a bunch of people that can't have guns. (Clause 1 is about ammo for a gun you are allowed to have) Since everyone agrees Mr. Haywood isn't allowed firearms I'm not going to quote all of that.
Take my word that the BB gun isn't a "semiautomatic military-style assault weapon". (That's also a long quote)
Pistol is defined as such:
MN Statute 624.712 said:
Subd. 2.Pistol. "Pistol" includes a weapon designed to be fired by the use of a single hand and with an overall length less than 26 inches, or having a barrel or barrels of a length less than 18 inches in the case of a shotgun or having a barrel of a length less than 16 inches in the case of a rifle (1) from which may be fired or ejected one or more solid projectiles by means of a cartridge or shell or by the action of an explosive or the igniting of flammable or explosive substances; or (2) for which the propelling force is a spring, elastic band, carbon dioxide, air or other gas, or vapor.
"Pistol" does not include a device firing or ejecting a shot measuring .18 of an inch, or less, in diameter and commonly known as a "BB gun," a scuba gun, a stud gun or nail gun used in the construction industry or children's pop guns or toys.
Bolding mine. So he's good there.
However, Minnesota does not seem to actually
define "firearm" in their criminal code. (Or at least I couldn't find it, and they have a pretty good search feature)
They DO however define firearm in their
Fish and Game statutes. It is defined thusly:
MN Statute 97A.015 said:
Subd. 19 .Firearm. Firearm means a gun that discharges shot or a projectile by means of an explosive, a gas, or compressed air.
I am not a lawyer, and have no idea if they can pull definitions from outside the criminal code, but that seems to be the ONLY place in the 2015 MN Statutes where the word "Firearm" is defined. And if they're using that definition, he's boned.
Perhaps one of our Lawyers could chime in?
