By my read of the law, here's an example situation:
You walk outside and see someone committing a felony.
You're empowered by the law to prevent the commission of a felony using reasonable force.
Any fight on the part of the criminal is unlawful and we regular citizens are empowered to continue meeting force with force, matching a criminal's escalation, all in the name of preventing the commission of a felony.
Presumably, if the criminal escalated the situation until you were in fear of great bodily harm or death, you would be justified in commensurate self defense.
Not that this is the smartest way to proceed, but it appeared to be correct by the book as far as I can tell.
