An officer is there to protect people, so if it involved breaking the law to do his /her job then the law should be irrelevant. as peoples welfare take precedence.
Being human and caring for people could cause an officer to pause and think that way. However there's no right way to do wrong. Following correct procedure at all times is what's expected of LEOs.
It would have to depend on the seriousness of the crime. Then again I would ask what crime did the particular officer commit to help save the person? If the crime was like breaking into a persons house to go after a suspect who barricaded himself inside then I would understand. I just do not know any good examples for this issue.I agree that it would depend on the situation. If they are helping someone who needs it, and the law they broke isn't that serious, I think it should be alright. I agree that the cop should be warned not to do it again if the crime wasn't that serious.
I would believe that the lines have always been blurred. I would depend on the officers best judgement on he case matter if he or she has to break the law to save someone else.I agree that if it was for the general welfare of an individual or even group of people, the lines blur a little bit.
