MN statute 624.714
Subd. 17. Posting; trespass. (a) A person carrying a firearm on or about his or her person
or clothes under a permit or otherwise who remains at a private establishment knowing that the
operator of the establishment or its agent has made a reasonable request that firearms not be
brought into the establishment may be ordered to leave the premises. A person who fails to
leave when so requested is guilty of a petty misdemeanor. The fine for a first offense must not
exceed $25. .....
(b) As used in this subdivision, the terms in this paragraph have the meanings given.
(1) "Reasonable request" means a request made under the following circumstances:
(i) the requester has prominently posted a conspicuous sign at every entrance to the
establishment containing the following language: "(INDICATE IDENTITY OF OPERATOR)
BANS GUNS IN THESE PREMISES."; or
(ii) the requester or the requester's agent personally informs the person that guns are
prohibited in the premises and demands compliance.
............
So hypothetically, if one were in place, such as a mall, where it says "guns are banned" while carrying, no crime has been committed unless they are asked to leave and do not comply?
And if there is an incident like that which took place in Omaha, and someone who was carrying (but had not been explicitly asked to leave) shot the gunman, they would also not be guilty of any crime?
Also, thanks ttousi for pointing out this statute in my other post.
