Kansas Statutes Chapter 22. Criminal Procedure § 22-2402. Stopping of suspect

(1) Without making an arrest, a law enforcement officer may stop any person in a public place whom such officer reasonably suspects is committing, has committed or is about to commit a crime and may demand of the name, address of such suspect and an explanation of such suspect's actions.

(2) When a law enforcement officer has stopped a person for questioning pursuant to this section and reasonably suspects that such officer's personal safety requires it, such officer may frisk such person for firearms or other dangerous weapons. If the law enforcement officer finds a firearm or weapon, or other thing, the possession of which may be a crime or evidence of crime, such officer may take and keep it until the completion of the questioning, at which time such officer shall either return it, if lawfully possessed, or arrest such person.
