This is an online legal update for Missouri law enforcement officers. The lesson addresses new cases issued by state and federal courts to guide police officers regarding:  whether a police officer may rely on a warrant to seize evidence of a crime when the warrant specifies one location but the officer seizes the property somewhere else; whether a suspect who recently used alcohol or drugs can “knowingly and intelligently” waive his or her rights; whether, if a police officer has a prosecutor review a warrant affidavit, a police officer will be entitled to qualified immunity from important errors or omissions the officer made in the affidavit; how long a police officer may keep a compliant, non-threatening individual in handcuffs during a Terry stop.
