KANSAS CITY, Mo. — According to the FBI, sovereign citizens believe they are separate from the United States and aren't required to answer to any government authority — including courts, motor vehicle departments, and law enforcement.

It often makes their interactions with police difficult. The Sugar Creek, Missouri, Police Department released body-cam footage Tuesday of one such recent interaction.

Aaron Fletcher identifies as a sovereign citizen. He refused to pull over for police, who were attempting to arrest him for outstanding warrants, and refused to get out of his car after pulling over near his home.

Police can be seen breaking the window and pulling Fletcher from the car.

While the investigation into the circumstances of that police stop continue, 41 Action News went in search of answers about the sovereign citizen movement.

"I have represented a few over the years," criminal defense attorney John Picerno said. "Their No. 1 belief is that they are not subject to the control of United States laws and that's simply not true."

For people who hold such beliefs, interactions with police often wind up quite confrontational.

"You add into the mix there someone who doesn't believe law enforcement officers have legal authority to apprehend, It's extremely difficult and ... that's why you see situations where you see officers using the force that they use to get that person out of the vehicle," Picerno said.

Dr. John Hamilton — a retired Kansas City, Missouri, police officer and Park University professor — said officers need to be familiar with the group or things can turn ugly.

"You don't know what you are dealing with either." said Hamilton, who teaches criminal justice at Park. "You don't know if someone who really is well-versed on all the laws that they read, the federal laws, that say they are empowered to do that. Then, some don't know those kind of things, but just decide that is sounds like something interesting to do."

It's also difficult for attorneys who represent "sovereign citizens."

"It's harmful for them, because they say those things in open court, they are seen as being in defiance of our laws and of our government," Picerno said. "Naturally, prosecutors and judges don't take very kindly to that kind of attitude."

Hamilton has advice to anyone who thinks they are above the law and are part of the movement.

"I would tell them the same thing I would tell anybody, which is to cooperate — to make sure you show your hands, to do what the officer tells you to do as long as it lawful, and appropriate," he said. "If you have problems, you can settle it at a later time."

Many metro police departments are working to address how to deal with such individuals. The KCPD trains recruits at the academy how to identify someone who is a sovereign citizen and also has an investigative unit that deals with incidents involving the movement.
