“If Zimmerman assaulted Martin, a felony, he cannot later claim self-defense if he is losing a fight he started himself. Self-defense cannot be claimed in commission of a felony.”
I’m pretty sure that you’re not under any obligation to allow yourself to be killed no matter what you did first if you’re not still an active threat.
True, but you cannot, as I understand it, claim self-defense and walk, as the SYG law allows.
You can (and should) be charged with something less than first-degree murder, possibly involuntary manslaughter.
