Section 6E:14 - No physical force to be used unless de-escalation tactics attempted(a) A law enforcement officer shall not use physical force upon another person unless de-escalation tactics have been attempted and failed or are not feasible based on the totality of the circumstances and such force is necessary to: (i) effect the lawful arrest or detention of a person; (ii) prevent the escape from custody of a person; or (iii) prevent imminent harm and the amount of force used is proportionate to the threat of imminent harm; provided, however, that a law enforcement officer may use necessary, proportionate and non-deadly force in accordance with the regulations promulgated jointly by the commission and the municipal police training committee pursuant to subsection (d) of section 15.(b) A law enforcement officer shall not use deadly force upon a person unless de-escalation tactics have been attempted and failed or are not feasible based on the totality of the circumstances and such force is necessary to prevent imminent harm to a person and the amount of force used is proportionate to the threat of imminent harm.(c) A law enforcement officer shall not use a chokehold. A law enforcement officer shall not be trained to use a lateral vascular neck restraint, carotid restraint or other action that involves the placement of any part of law enforcement officer's body on or around a person's neck in a manner that limits the person's breathing or blood flow.(d) A law enforcement officer shall not discharge any firearm into or at a fleeing motor vehicle unless, based on the totality of the circumstances, such discharge is necessary to prevent imminent harm to a person and the discharge is proportionate to the threat of imminent harm to a person.(e) When a police department has advance knowledge of a planned mass demonstration, it shall attempt in good faith to communicate with organizers of the event to discuss logistical plans, strategies to avoid conflict and potential communication needs between police and event participants. The department shall make plans to avoid and de-escalate potential conflicts and designate an officer in charge of de-escalation planning and communication about the plans within the department. A law enforcement officer shall not discharge or order the discharge of tear gas or any other chemical weapon, discharge or order the discharge of rubber pellets from a propulsion device or release or order the release of a dog to control or influence a person's behavior unless: (i) de-escalation tactics have been attempted and failed or are not feasible based on the totality of the circumstances; and (ii) the measures used are necessary to prevent imminent harm and the foreseeable harm inflicted by the tear gas or other chemical weapon, rubber pellets or dog is proportionate to the threat of imminent harm. If a law enforcement officer utilizes or orders the use of tear gas or any other chemical weapon, rubber pellets or a dog against a crowd, the law enforcement officer's appointing agency shall file a report with the commission detailing all measures that were taken in advance of the event to reduce the probability of disorder and all de-escalation tactics and other measures that were taken at the time of the event to de-escalate tensions and avoid the necessity of using the tear gas or other chemical weapon, rubber pellets or dog. The commission shall review the report and may make any additional investigation. After such review and investigation, the commission shall, if applicable, make a finding as to whether the pre-event and contemporaneous de-escalation tactics were adequate and whether the use of or order to use such tear gas or other chemical weapon, rubber pellets or dog was justified.Mass.
