One may morally and legally in the clear at the time of the fight. One may need the authorties to ensure that one STAYS morally and legally in the clear, and not the subject of a criminal investigation or a liability suit sometime after the fact.
Whether the person needs my aid or not, I would be calling 911. I want all the first responders by my side. Fire fighters are often first on the scene. They have oxygen and strong responders to lift the person out of danger. The police can investigate and give me a report that clears my name. The paramedics can make the determination if medical attention is needed...they are a better judge of it than I am.
The other aspect...disease is risked in a fight, I won't risk it further by not having gloves, etc. to properly treat a person. Plus, my First Aid cert is 20 years out of date. Much better to have the paramedics involved...even if the attacker says s/he is NOT hurt.
