Contains provisions relating to law enforcement officer accountability

HB 1953 revises Missouri's law enforcement accountability standards by replacing existing statutes with five new sections. It clarifies that officers may only use force they reasonably believe is necessary to make an arrest, with deadly force permitted only in specific situations like when a person is committing a violent felony or threatening serious harm. The bill requires officers to intervene and report excessive force by colleagues during arrests or crowd control, and prohibits retaliation against officers who report misconduct. It also mandates immediate dismissal and license revocation for officers using respiratory choke-holds outside of specific exceptions. These provisions directly affect all Missouri law enforcement officers and their agencies.
