What Do Weapon Laws Cover in Kansas City, MO?

MO law covers topics like purchase, possession, and use of guns and other weapons. But that’s not all you have to worry about in MO: There are still federal laws that affect the availability and use of self-defense tools. For example, MO does not address background checks in the sale or transfer of firearms, but federal law requires licensed dealers to conduct one, meaning that most MO gun transfers still require a background check.

In MO, the majority of people are permitted to carry a self-defense weapon, as long as:

  1. They do not carry it into certain locations, including schools, government buildings, airports, churches, etc., and
  2. Nothing has happened to lead that person to lose their right to carry a weapon.

In MO, you’re allowed to use your gun at the range and for self-defense, but several other activities are illegal. These actions mostly are those that would endanger others, such as using the gun in a threatening manner, bringing one to a polling place during an election, or using one while committing another crime.

One quick note – although we focused on state regulations above, MO allows for individual municipalities to enforce their own more stringent laws regarding firearms and other weapons, so to ensure you’re compliant with regulations in Kansas City, be sure to go over your local statutes and connect with a gun crime lawyer if you’re unclear on any regulations.

Weapon Crimes Defenses We Use in Kansas City, MO

Weapon crimes are, on a fundamental level, just like most other criminal allegations: You are charged, negotiate, and if necessary, go to trial. That said, they are more likely to involve tactics like claiming self-defense, and defenses frequently have less to do with whether you “did it” and more on whether what the defendant did was “justified.”

Below, we’ve listed common defense tactics we might use in your defense against Kansas City, MO, weapon crimes allegations:

  • Self-Defense: Weapons are frequently used in self-defense, and related criminal charges can may not actually be applicable to you. In Missouri, you are allowed to take actions to protect yourself from imminent danger.
  • Defense of Others: Related to self-defense, you are allowed to use force to defend another person. Some weapon charges can be related to this in the same way that they can be related to self-defense.
  • Castle Doctrine: MO castle doctrine says that you are sanctioned to use force, including weapons, to protect yourself and other people at your residence. While you do not have a duty to retreat, the force used needs to be proportionate to the threat.
  • Stand Your Ground: Stand your ground is built off of castle doctrine. The state of Missouri states that you can use force and/or weapons to defend yourself, even outside of your home, as long as you are allowed permitted to be wherever you are.
  • Necessity: Necessity applies to situations where you were forced to do something illegal in order to stop something worse. Perhaps you knew someone at risk of self harm, and to protect them, gave their weapons to someone who legally wasn’t allowed to possess them. This is technically against the law, but you needed to do so to prevent a greater harm.
  • Duress: When you unwillingly broke the law, because another person forced to do so, you can claim duress as a defense. An example of this might be if you removed the serial numbers of a firearm, defacing it, but only did so because someone threatened you.
  • Lack of Intent: If you didn’t mean to break the law, depending on what exactly it was, a lack of intent can protect you from punishment. For example, giving a blackjack to an underaged person without permission is illegal. If you honestly thought this person had parental permission, though, you could be exempt due to a lack of intent.
