Section 3.  (a) Any officer present and observing another officer using physical force, including deadly physical force, beyond that which is necessary or objectively reasonable based on the totality of the circumstances shall intercede to prevent the use of unreasonable force, unless interceding would result in imminent harm to the officer or another identifiable individual.

(b) An officer who observes another officer using physical force, including deadly physical force, beyond that which is necessary or objectively reasonable based on the totality of the circumstances shall report the incident to their direct supervisor as soon as reasonably possible, but no later than the end of the officer’s shift.

(vi) the duty of officers to intervene pursuant to section 3; and

(vii) comprehensive reporting protocols pursuant to section 35 of chapter 12.

SECTION 6. Chapter 276 of the General Laws is hereby amended by inserting after section 2C, as appearing in the 2018 Official Edition, the following section:-
