Here's one in which the defendant won his appeal for a felon in possession charge due to self-defense. He was also found not guilty of attempted manslaughter:

Here is one in which a robbery was committed against a person in possession of drugs & dealing paraphernalia (with which he was charged but not charged with murder). The robbers were convicted of murder when the victim/dealer killed one of the other robbers with his (the victims/dealers) gun. It looks exactly like the possible case of the student defending himself against a robbery:
Exum vs State
I'm sure there are more but these are the two I could find fairly easily.

Now that I've looked it up I find that killing someone while trying to deal drugs is murder & I don't think self-defense can be asserted for those charges since it is specifically written into the IC.
That doesn't square with the above case where the guy wasn't charged with murder when he defended himself from a robbery AND was charged with dealing.
I guess the bottom line is that not ALL felonies bar you from using self-defense, only the ones specifically listed in the IC for murder. Most are just common sense. Namely,
and drug dealing.
Well, I guess I just don't know now, either.
I have a friend who is a deputy prosecutor. I will try to run it by him.
