1) Brandishing & 2) Improper Carry of a Firearm at the very least.
1 - Using a weapon with the intention of influencing the behavior of another #Felony
2 - All Openly Carried firearms MUST be carried using a sling, scabbard or holster. #Misdemeanor
Additionally, if this person does not have an OKLAHOMA handgun license (a real possibility since Constitutional/Permitless Carry went into effect on 1 November 2019) and was at any time on any public property within 1000 feet of a school, the he has also violated the Federal Gun Free School Zones Act of 1990 (by Joseph R. Biden). #FederalOffense $5000 fine, 5 years in prison and become a lifetime prohibited individual.
