Watch and listen as this very respectful policeman explains the open carry laws in Missouri.
This law enforcement office was kind and very positive as he detailed the MO carry laws to several out-of state young ladies. It seems the young women had legal firearms, were accustomed to open carry, and attempted to open carry in a Walmart.
This is a good primer for learning a states carry laws prior to a visit.
But 2 thumbs up for this thoughtful policeman who reiterated that he, and most of the LE in the Springfield area are pro-gun, pro-Second Amendment.
