(1) As used in this section, "misconduct" means:

(a) Unjustified or excessive force that is objectively unreasonable under the circumstances or in violation of the use of force policy for the law enforcement unit employing the offending officer

(b) Sexual harassment or sexual misconduct

(c) Discrimination against a person based on race, color, religion, sex, sexual orientation, national origin, disability or age OR

(d) A crime

(2) Without regard to rank or assignment, a police officer or reserve officer shall intervene to prevent or stop another police officer or reserve officer engaged in any act the intervening officer knows or reasonably should know is misconduct, unless the intervening officer cannot intervene safely

(3)(a) A police officer or reserve officer who witnesses another police officer or reserve officer engaging in misconduct or a violation of the minimum standards for physical, emotional, intellectual and moral fitness for public safety personnel established under 181A.410 (Minimum standards and training for certification) will report the misconduct or violation as soon as practicable, but no later than 72 hours after witnessing the misconduct or violation, to:

(A) A direct supervisor of the reporting officer

(B) A person in the reporting officer's chain of command OR

(C) DPSST

(b) If the person to whom a police officer reports misconduct or a violation under this paragraph doesn't have the authority to direct an investigation into the alleged misconduct or violation, the person will forward the report of misconduct or violation to someone who has the authority to direct an investigation into the alleged misconduct or violation as soon as practicable, but no later than 72 hours after receiving the report

(c) A law enforcement unit that receives a report of misconduct or violation under this paragraph will complete an investigation of the misconduct or violation within three (3) months after the date of the report unless circumstances prevent the investigation from being completed. The law enforcement unit will notify the DPSST when an investigation results in a finding that sustains a report of misconduct, but need not notify the department when an investigation results only in a finding that sustains a report of a violation of the minimum standards for physical, emotional, intellectual and moral fitness for public safety personnel established under 181A.410 (Minimum standards and training for certification)

(4) Failure to intervene or report as required by paragraphs (2) and (3) of this statute is grounds for disciplinary action against a police officer or reserve officer by the law enforcement unit employing the officer or for DPSST to suspend or revoke the officer's certification as provided in 181A.630 (Procedure for denial, suspension or revocation of application or certification), 181A.640 (Grounds for denial, suspension or revocation of application or certification of person or accreditation of program) and 181A.650 (Judicial review of department's final order)

(5) An employer may not discharge, demote, suspend or in any manner discriminate or retaliate against a police officer or reserve officer with regard to promotion, compensation or other terms, conditions or privileges of employment for the reason that the officer intervened or reported as required by paragraphs (2) and (3) of this statute. Violation of this subsection is an unlawful employment practice as provided in 659A.199 (Prohibited conduct by employer)

(6) DPSST will report at least annually to an appropriate committee of the Legislative Assembly on any rules adopted by the department implementing this statute
