As I understand it, in WV, you can be asked to leave the premises or check your weapon. If you refuse, then you can be charged with trespassing. My guess is, if you are not asked to do either one, then the business owner doesn’t have a leg to stand on, even in the event that something happens, since you have to be asked to leave or check your firearm first.
“Any person carrying or possessing a firearm or other deadly weapon on the property of another who refuses to temporarily relinquish possession of such firearm or other deadly weapon, upon being requested to do so, or to leave such premises, while in possession of such firearm or other deadly weapon, shall be guilty of a misdemeanor, and, upon conviction thereof, shall be fined not more than one thousand dollars or confined in the county jail not more than six months, or both.”
If there is no confrontation, there can be no violation. A sign is not, for purposes of the law, considered a confrontation.
I am not a lawyer, but this is the assumption under which I carry in WV...I’d rather be judged by twelve than carried by six.
Missouri’s law is the same, you are asked to leave with your weapon. No charges unless you refuse to leave.
