This is an online, Missouri-specific legal studies course. The lesson addresses recent court decisions providing guidance to Missouri law enforcement officers regarding: 

• Whether a Missouri peace officer’s license may be permanently revoked for committing a domestic assault;

• When it is necessary for law enforcement officers to provide Miranda warnings; 

• Whether a suspect has Fourth Amendment protection in his or her text messages sent to another person’s phone that police have the authority to search; and 

• Whether officers may extend a traffic stop to investigate suspected criminal activity unrelated to the original mission of the stop.
