There is a movement to convince store owners in Seattle to post No Guns Allowed signs at their entrances. It is a violation of trespass law to knowingly enter a businessmen properly signed. I would have no problem entering such an establishment, because I could always claim I didn't see the sign if I were made, but the police encourage owners to call 911 in such a situation so the police can make the confrontation and ask the violator to leave. While it seems like an arrest would be unlikely if one complied and quickly left, the law is written in such a way that an arrest would be justified, unless there is established case law to the contrary. It's just easier to refuse to patronize a business that touts itself as anti-gun and, thus, anti-civil rights.
As I stated, I don't believe his intent was to condone breaking any laws.
In Missouri the signs that you mention went up like a wildfire taking a dry grass field during a drought when the state adopted a CCW program to permit the average citizen to do so. What I noticed, is that roughly 75 to 80% of those signs initially posted were not legal signs based on the minimum size required by state law, so in essence meant nothing. Another thing that I noticed was the slow disappearance of those signs through the years, the majority of which have gone away in the last two to three years. Not sure what the motivator for that is and I don't really care to speculate, I just know that better than half of the places that used to display them no longer do so.
Excluding any place prohibited by federal law, doing so would obviously be a felony, Missouri state law is actually rather "common sense" motivated in my opinion when considering other locations not regulated under federal law.
The only two instances that I'm aware of that are actually considered a crime by the state involve public transportation, public buses being a felony, and public trains being a misdemeanor. Following is a list of places that carrying is in fact NOT considered a crime in the state of Missouri, and an explanation of the repercussions should one be found out to be and then refuse to leave voluntarily.
"A ccw permit does not authorize any person to carry concealed firearms into the 17 locations specified below.
Doing so is not a criminal act under Missouri law, but may subject the person to denial to the premises or removal from the premises. If the individual refuses to leave after being asked and the police are called, he or she may be issued a citation for an amount not to exceed $100; a second offense within 6 months is a $200 fine and suspension of the ccw permit for one year; a third offense within 12 months is a $500 fine and the loss of the ccw permit for 3 years.
1.Any police, sheriff, or highway patrol office or station without the consent of the chief law enforcement officer in charge of that office or station
2.Within twenty-five feet of any polling place on any election day
3.The facility of any adult or juvenile detention or correctional institution, prison or jail
4.Any courthouse or building used by a court
5.Any government meeting including state legislature
6.Government owned buildings except public housing
7.Bars (except owners)
8.Any area of an airport to which access is controlled by the inspection of persons and property
9.Any place where the carrying of a firearm is prohibited by federal law (crimes fall under federal law)
10.Any school (including colleges) without the consent of the governing body of the higher education institution or a school official or the district school board
11.Any child care facility without the consent of the manager

16.Any sports arena or stadium with a seating capacity of five thousand or more
17.Any hospital accessible by the public"
I believe that I can promise you that I'll not be paying any fines or having my ccw permit suspended for stupidity on my part.
Maybe my perspective is wrong, but I think that Missourians have begun to look at the concept of CCW holders in our state sensibly and our laws have begun to reflect that sensibility... that kind of makes me proud.
