You are out with friends in Kansas City when a confrontation turns violent. Your instinct tells you to jump in and protect your friend from harm.
While your intentions are good, police may not see it that way. You could find yourself facing assault charges for a fight you did not start.
Understand your legal rights
Missouri law allows you to use force to protect another person in specific situations, under a legal category called “justification.” You must believe that the other person faces an immediate threat of physical harm. The law requires that you use only the amount of force necessary to stop the danger.
Using excessive force beyond what is required to neutralize the threat could result in you losing legal protection. Missouri courts evaluate your actions based on what a “reasonable person” would do in your position.
When the law protects your actions
Protecting someone else is a high-stakes decision. The following factors often determine if your intervention is justified:
- The person you are defending did not start the fight.
- The threat of harm is immediate, not in the future.
- You used only the force required to stop the attack.
- A neutral observer would agree that the person you helped faced real danger.
- You “reasonably” believed your intervention was necessary to prevent injury.
Missouri law generally protects you even if you defend the “initial aggressor,” provided that the person you are assisting clearly retreated, and the other party continued the attack. You must stay alert to how the situation shifts to maintain your legal defense.
In Missouri, you also benefit from “Stand Your Ground” protections. This means you have no legal duty to retreat from any place you have a right to be before using force to protect yourself or another.
Additionally, a recent case in which the Missouri Supreme Court declined to overturn an appellate ruling on deadly force illustrates how these standards continue to evolve, potentially expanding the circumstances under which a person can legally defend themselves or others.
Proving the truth
Law enforcement officers often arrive after a fight ends. They may only see the aftermath and rely on biased statements from the other party, which frequently leads to police handcuffing and processing the wrong person.
An experienced criminal defense lawyer knows how to rebuild the scene using objective evidence. The process often involves gathering video from security cameras and finding witnesses who saw the beginning of the scuffle. An attorney works to ensure the prosecutor sees the full story, not just the final moments.
The justice system is complex, and the consequences of an assault conviction can last a lifetime. Skilled legal guidance ensures the court hears your side of the story and upholds your rights, so that you can move on with your life without a criminal record.
