39Force used in executing process or in arrest

1. Where any person is justified, or protected from criminal responsibility, in executing or assisting to execute any sentence, warrant, or process, or in making or assisting to make any arrest, that justification or protection shall extend and apply to the use by him or her of such force as may be necessary to overcome any force used in resisting such execution or arrest, unless the sentence, warrant, or process can be executed or the arrest made by reasonable means in a less violent manner:

   provided that, except in the case of a constable or a person called upon by a constable to assist him or her, this section shall not apply where the force used is intended or likely to cause death or grievous bodily harm.
